not enough space in left panel for trace expansion?

**Original reporter**: _kowey_

Another possible wont-fix:

To my screen, the left panel is wide enough to display a list of traces with checkboxes. If you expand any of the trace tree and then collapse it again, the checkboxes disappear, presumably because they are too far to the right.

Only reporting this because it can be easy to expand the traces by accident if you just click on them, for example, and the checkboxes disappearing can be a little bit confusing.
