Steps to reproduce the problem:
1. Refresh the page
2. Quickly press Ctrl-F

It may take about 10 tries to reproduce the bug, it seems to happen only when you open it at a certain moment in the load process.

What is the expected behavior?

What went wrong?
The search bar does not appear, but you can type to find (highlight) words on the page (as if you were typing in an invisible search bar). Closing it and re-opening it does not make it appear, but switching tabs does.

Did this work before? N/A
