Fix flairselection dropping under elements

Changing the opacity of elements messes with their z-index. I got the following screenshot from a person using our mod toolbox extension:

On investigation I found that it was not toolbox or RES related but rather the fact that shadowbanned submissions have an opacity of 0.7. Removing the opacity and setting a background resulting in the same color instead fixes this issue.
