Left/right arrows for navigating pages where there are a lot of tabs don't appear, and shortcuts to change page selection don't work

[roachcord3]

Environment

Hydrus version: 426 via executable Platform: macOS OS specifics: macOS Catalina 10.15.7

What happens

Left/right arrows for navigating pages where there are a lot of tabs don't appear, and shortcuts to change page selection don't work. This feels OS specific.

(Update over 3 years later: still a problem despite a major Qt version upgrade, multiple OS upgrades, and over 50 releases!)

Steps to reproduce

1. Just create a lot of pages, to the point where the tab bar can't hold them all
2. Notice that no left/right arrows appear anywhere to allow for navigating through them
3. Bind some shortcuts to change page selection (either move page selection left/right or move selection to leftmost/rightmost page work)
4. Try the shortcuts
5. Notice that nothing will happen

Desired outcome

Some sort of left/right arrows should appear to allow navigating between pages, and shortcuts to move between pages should work too
