Selector: Remove an obsolete comment

mgol · web-flow · commit 14685b318ae0 · 2023-04-03T18:16:43.000+02:00
There was a comment claiming that there are two implementations of `safeActiveElement`. However, the one in `event.js` got removed in gh-5224, even before the comment was added. This commit removes this obsolete comment. Closes gh-5237 Ref gh-5224
