Pull Request Overview

This pull request refactors internal status management by moving the parent component unique identifier from runtime state into a DOM attribute, supporting SSR for Web.

• Replace usage of the getElementByUniqueId symbol with accessing runtime[lynxUniqueIdToElement] and dereferencing elements.
• Update element creation logic to set a parent component unique ID attribute (using new constant names) on page elements rather than in runtime info.
• Adjust constants definitions to use shorter attribute names for brevity and consistency.

File	Description
packages/web-platform/web-mainthread-apis/src/elementAPI/event/eventFunctions.ts	Refactored how parent component IDs are retrieved, now converting an attribute to a number and using the new runtime mapping.
packages/web-platform/web-mainthread-apis/src/elementAPI/elementCreating/elementCreatingFunctions.ts	Updated element creation to remove runtime state for parentComponentUniqueId and instead set it as a DOM attribute.
packages/web-platform/web-mainthread-apis/src/elementAPI/ElementThreadElement.ts	Removed the now-unused parentComponentUniqueId from the runtime info interface.
packages/web-platform/web-mainthread-apis/src/MainThreadRuntime.ts	Removed the deprecated getElementByUniqueId function in favor of the updated lookup mechanism.
packages/web-platform/web-constants/src/constants.ts	Updated attribute constants with shorter names and introduced a new constant for the parent component unique ID.
.changeset/busy-suits-build.md	Updated versioning and changelog to reflect these refactoring changes.

• Consider verifying that the parentComponentUniqueId attribute exists and is a valid number to prevent potential runtime errors in SSR scenarios.

const parentComponentUniqueId = Number(currentTarget.getAttribute(parentComponentUniqueIdAttribute)!);

packages/web-platform/web-mainthread-apis/src/elementAPI/elementCreating/elementCreatingFunctions.ts:115

• Ensure that setting the parent component unique ID to '0' for page elements aligns with the intended SSR behavior across the codebase.

page.setAttribute(parentComponentUniqueIdAttribute, '0');

Pull Request Overview

This PR refactors several internal state mappings onto DOM attributes to enable server-side rendering (SSR) support.

• Renames and centralizes attribute names (unique ID, CSS ID, component ID) to shorter l- prefixed attributes and adds l-p-comp-uid and l-dataset.
• Updates serialization, event handling, element creation, and dataset functions to read/write from these new attributes instead of runtime maps.
• Removes the getElementByUniqueId symbol/method and adjusts snapshot tests to match the new attribute output.

• This implementation reparses the entire dataset JSON on each call; for large datasets, consider caching the parsed object (e.g., in a WeakMap) to avoid repeated JSON operations.

function __GetDataset(
      element: HTMLElement,
    ): Record<string, any> {

• [nitpick] Most attributes have been renamed to the l- prefix; to maintain consistency, you may want to rename lynx-tag to l-tag or document the exception clearly.

export const lynxTagAttribute = 'lynx-tag' as const;

packages/web-platform/web-mainthread-apis/src/elementAPI/attributeAndProperty/attributeAndPropertyFunctions.ts:42

• None of the new dataset-related functions (__GetDataset, __SetDataset, __GetAttributes) appear to have dedicated unit tests; consider adding tests to validate correct encoding/decoding and merge behavior.

function __GetAttributes(
      element: HTMLElement,
      key: string,
