Image toolbox transparency bug.

Hi!

I think I've found a bug in the forums.

I am on a Firefox-based browser on Windows 11.

When I open the "Insert an Image" toolbox the new window sometimes gets stuck in a half-transparent mode. This happen both in the Answer and in the Meta forum. Everything withing the Image toolbox window is accessible as normal.

This usually gets solved by closing and opening the Image toolbox window a couple of times.

Example:

Thanks a lot,

Cheers
