Rollup merge of #67527 - GuillaumeGomez:results-show-too-much, r=kinnison

Browse source 
Results show too much

Fixes #67461.

To reproduce the current issue: search anything, then once the results appears, press escape. They should disappear then re-appear right away. This is because blurring an element triggers the "change" event.
