Using a Widescreen Monitor 3840x1600, but seems to occur on every screen.

Description:
In management screens (e.g. fleet, planet, production), switching between tabs causes issues with list height calculation. If the first tab contains a list short enough to fit fully within the viewport and then the player switches to a tab with a longer list, the container height is not recalculated. As a result, the scrollbar does! appear, but its too short and lower entries cannot be reached.

Steps to Reproduce:

1. Open a management screen.

2. Select a tab that shows a short list (fits fully on screen).

3. Switch to another tab with a list longer than the screen height.

4. Observe: the scrollbar is there, but wrong height, and scrolling is slightly possible, but just a few (50) pixels.

Expected Result:
When switching tabs, the container height should be recalculated and a scrollbar should appear for longer lists.

Actual Result:
Scrollbar does not appear after switching to a longer list. The container remains fixed at the previous (shorter) height.

Frequency: Always reproducible

Workaround: Closing and reopening the list restores correct container height and enables scrolling.

Thank you.
