Inconsistent Behavior of IsSpellCheckEnabled and IsTextPredictionEnabled on Entry Control

[LogishaSelvarajSF4525]

Description

The IsSpellCheckEnabled and IsTextPredictionEnabled properties on input controls such as Entry do not behave consistently across platforms.

On Android and Windows:

• The properties sometimes work as expected—enabling spell check suggestions and text prediction.
• However, when IsSpellCheckEnabled is set to true, the system may autocorrect misspelled words instead of showing a squiggly underline, which is not the expected behavior. This reduces user control and can lead to unintended text changes.

On iOS and Maccatalyst:

• Toggling IsSpellCheckEnabled and IsTextPredictionEnabled has no observable effect.
• No spell check underlines or predictive suggestions appear.
