Scrolling behaviour of large modules

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Discovered an UI quirk of Spektrafilm large modules like Spektrafilm or AgX, probably linked to the vertical height @piratenpanda but I think this might be one for @Arecsu as the behaviour is inconsistent:

When clicking the tabs of spektrafilm the right panels scrolls upwards until the tabs are in the upmost position. After double-clicking a tab (did this after going through all tabs in the video above) this behaviour stops and the scrolling position stays put. After collapsing and expanding spektrafilm it scrolls on it's own again.

Steps to reproduce

see above

Expected behavior

darktable should behave!

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip

No response

Start by reproducing the behavior shown in the attached screencast with the Spektrafilm or AgX modules on Linux, using the reported darktable AppImage context. Check tab selection, double-clicking, and collapsing or expanding the module; done means the right panel no longer scrolls unexpectedly and behaves consistently across these actions.
