Pop-up job list from pipeline creates horizontal scrollbar on main window
Summary
Clicking on the stage icons for a pipeline in a MR page pops up a list of jobs. When this list is long, it has a vertical scrollbar itself, and when it is right-aligned, the list (with scrollbar) ends up being too wide and causes an horizontal scrollbar to appear for the main window.
Steps to reproduce
Set Fluid layout in preferences. Create a MR with a pipeline that has a stage with a few (probably more than 6) jobs. The MR page will have a widget for the pipeline, with one or more right-aligned icons showing the status of the different stages. Click on the rightmost icon.
Example Project
An example MR: Molcas/OpenMolcas!285 (merged)
What is the current bug behavior?
An horizontal scrollbar appears in the main window and the vertical scrollbar in the list is not visible:
What is the expected correct behavior?
The list should be narrower or displaced to the left.
