There was a problem hiding this comment.
Consider updating the XML documentation for RecalculateSpanPositions to document the new 'size' parameter and its role in reflecting the arranged bounds from LabelHandler. This will help maintain clarity for future developers maintaining this internal method.

Issue Details:
The Tapped event or Command of the TapGestureRecognizer is not triggered for span text when tapped on iOS and Mac platforms.
Root Cause:
In the RecalculateSpanPositions method of the FormattedStringExtension class, span regions are created only when the native bounds are greater than 0. In our scenario, the native bounds of the Label were 0 when its visibility changed from false to true. So, we added an early return in the RecalculateSpanPositions method when the native bounds are 0, preventing the creation of invalid span regions.
Description of Change:
Since RecalculateSpanPositions is invoked from the ArrangeOverride method in LabelHandler.iOS, where the actual size of the label is available, I modified the logic to pass the correct bounds from the Arrange step. These bounds are then used in RecalculateSpanPositions to create span regions, instead of relying on potentially outdated native label bounds.
Tested the behavior in the following platforms.
