The mouseover and selected highlights in the tabbar of the editor are gone. I think this was introduced in PR #15124.

Ok, so in order to reduce the number of variables, I just did a fresh install of Anaconda and installed Spyder dependencies in a fresh new Python 3.8 environment (instead of 3.7) with conda install -c spyder-ide/label/dev --file requirements\conda.txt.

Everything now looks fine, so I think we can safely close this issue, since the problem was most likely due to my environment which was kind of outdated.
