Bug report

Environment:

• Firefox 85 on Windows
• 1920x1080 resolution

Steps to reproduce:

1. In top navigation bar, tap "PROJECTS".
2. Tap "zNote", a "Znote project" dialog appears.
3. In top navigation bar, tap "ABOUT".

Expected behavior: either "ABOUT" is unselectable, or the "Znote project" dialog disappears.
Actual behavior: the page scrolls, but the "Znote project" still stays on top.
