Fix 1.7.5 not opening search w/hotkey + focus lock

Older versions of Obsidian focused the search box directly from the search command, which allowed hotkey-based search to work with Pane Relief's Focus Lock active. Newer versions now do the focusing in a way that is subject to Focus Lock, so this release adds a workaround to emulate the old behavior.

Note: with the exception of taking focus away from popout windows, Obsidian has fixed most of the problems in its UI that Focus Lock was intended to prevent, so you may want to try turning off Focus Lock to see if you still need it. (The one other major use case for it is keeping the "Automatically reveal active file" plugin from constantly focusing the file explorer pane.)
