Typing in Regex Tester makes it not disappear when switching tools

[MathiasLui]

Describe the bug

Visiting the "Regex Tester" tool, typing anything into the first "Regex to test" box, and then trying to switch to any other tool results in the Regex Tester content not disappearing until reloading the page.

Happens both on the main page and on self-hosted, no other tools have been checked for this behaviour.
