Branch label background misaligned when containing multi‑line text in LR layout (GitGraph)

[Qfield]

Description

When using GitGraph with the LR (left‑to‑right) layout, branch labels that contain multi‑line text are not vertically aligned with their background rectangle. The background box appears higher than the text, causing a visual offset.

Steps to reproduce

1. Create a GitGraph instance with layout: "LR".

2. Add a branch and set its label to a string that includes line breaks (e.g., "Feature A\n(ongoing)").

3. Render the graph.

4. Observe the branch label: the background rectangle is positioned higher than the text block.
