[Windows] - Top Tab Visibility Changes Not Reflected Until Tab Switch

Description

When attempting to hide top tabs (TopTab2, TopTab3) from the main tab using the visibility buttons, the UI does not immediately reflect the visibility changes. The tabs remain visible until the user navigates to a different bottom tab (Tab 2 or Tab 3). Only after switching tabs the visibility changes take effect.
