Description

Description

Tab pages in a TabbedPage do not disappear when their IsVisible property is set to False. Instead, the tab remains, but the content of the tab is blank. Not entirely what one would expect.

Steps to Reproduce

  1. Set up a TabbedPage with some tab pages
  2. Set one of the pages' IsVisible property to False
  3. Observe that the page tab does not disappear

Expected Behavior

The entire page is no longer visible.

Actual Behavior

The page tab is visible.

Research direction
Inspect the TabbedPage renderer and platform specific implementations to understand why IsVisible does not hide the tab. Trace the property change handler and check for any missing updates.
