Window adjustment arrow still appears after closing the left sidebar，in zotero7

Winterchan

As the title suggests, the window adjustment arrow still appears after the left sidebar is closed, which is very inconvenient when copying text in that area.

When the left sidebar is not closed, the adjustment arrow appears normally：

Does it occur with all the plugins disabled? There is a suspicious space before the PDF tab which seems to align with the arrow.

Yes, This situation still occurs when I disable all plugins. Before the PDF tab is the library tab without any spaces.

(Side note

Before the PDF tab is the library tab without any spaces.

Right, I have several tabs opened, so I don't see this large space, but with only one tab opened, I can see it. Maybe this could be fixed)
