Fix #76151

Part of #76515

This reverts commit 9f86032f.

Get rid of the "current match" debouncer because now the selection and focus are synced by the navigator anyway, and that's fine.
Now the only debounce is on the open event coming from the navigator.
Also, change the navigator onFocus to respect the browserEvent's preserveFocus which should be ok

This is broken and I don't really like this behavior anyway

We shouldn't trim here because this chunk can be the middle of a result line. Saw this removing spaces from the result text, resulting in a miscount later on
