Release v125.0rc2

I wasn't going to make this a release and instead wait until 125 official launch and a few other changes. However I forgot to disable PGO, and since I have it, I figured I might as well release it.

This release fixes the listbox dropdown icon having no background.

Haven't tested on XP/Vista (extended kernel) nor have I stability tested.

Please let me know what bugs or issues you encounter with it.
