Description

It is possible to use mouse wheel and scroll through opened files in editor.
Scrolling is broken in Usages tab when FlatLaf Dark Look and Feel is used.

Steps to reproduce:

1. Open Java source file.
2. Repeatedly invoke Find Usages action until there are more result tabs under Usages panel.
3. Try scrolling with mouse wheel when on tabs with usage results.

Switching from FlatLaf Dark to another LaF (tried GTK+) restores ability to scroll.
