Grid view in 44.2 too wide — horizontal scrolls content instead of fitting to window

Affected version

• Nightly flatpak: No (but the cause is a workaround in 44.2)
• Other: 44.2-1 on Arch Linux

Steps to reproduce

1. Switch to Grid View
2. Go into a directory with many files, such that they don't fit on one row

Current behavior

The filenames in the far right column of the grid appear partially cut off, but actually padding/margin is too much and it makes the grid horizontally scrollable.

See below screenshot for an example. For non-maximized windows the same can be observed; it may take changing the window width to happen. It seems the worst in maximized windows.

Expected behavior

The grid view only scrolls vertically, not horizontally.

Additional information

I bisected it to this commit: e193b2ce.
