Ok, I think I have understood, but I do not think this is new to 1.15. Checking
It changed between 1.14 and 1.15. ;-) That screenshot is from 1.14, before I upgraded it to test for #2600, after which it changed to the 1.15 situation as in the OP.
Ok, just checked and seems indeed new
Hum, I cannot immediately spot a CSS or JavaScript change which could relate to that.
Perhaps it's my own fault. ;-)

The fix is likely to look very similar.
Fixed by #2611 and #2612.
