This looks fine for me on GTK. The only part that is a problem is that the scrollbar isn't shown at the start if it is needed. It is only shown when the panel is resized the first time.
When I started it I had the little triangle or arrow on the left, I guess intended to "scroll" the tabs. But clicking that does not make the second tab appear.
Is there any reason for that panel to be that narrow by default? I mean this is close to being the main interaction with the pl_editor the user will ever use except for moving objects around graphically.
No, it should ideally be the correct size to show all pieces by default. The other thing is though, I think the width is saved in the preferences, so even making it the correct size will only work for people who delete all old preferences and start fresh.
For me the behavior is pretty much the same.
I can make the properties window wider, but there is no live update as compared with for example the layers window in Pcbnew.
There is also no vertical scrollbar and stuff starts disapearing when the total height of the window becomes less then 1030 pixels, which may be quite a nuisance for people working on a laptop (or PC) with a lowish resolution.

Can the fix be cherry picked to 5.1, too? A user asked about the missing scrollbar in 5.1 in the forum.
Vertical scrolling was the most important problem, but the panel still needs complete layout redesign. I should report another issue for that, I guess, unless it's agreed that this issue can be reopened.
