What happened?

On closing trainrun-and-section-tab component (cross button or outside the component), when closing it, a white rectangle appears on the right of the component. See video

Enregistrement.de.l.ecran.2026-01-08.114739.mp4

I would expect no rectangle to be shown afterwards

Nice spot. I tested it with Microsoft Edge and Google Chrome and couldn’t reproduce the issue in either browser. However, with Firefox I see the same behavior on both Firefox for Linux (Ubuntu) and Firefox on Windows 11.
