Bug during search-everything (Firefox Broswer)

Whenever I do a search in the browser version of Monday (here shown in Firefox), the white background only extends as far as the window is wide. As soon as I scroll to the side, for example when a task is longer than the screen, the white background just ends. It makes it nearly impossible to read the titles of the columns.
I’ve attached a screenshot to show what I mean.
It’s not a terrible bug, but a very annoying one.
