Add condition to refreshVisibleSearch in NotesEditor refs #942

[meusistemabr]

What kind of change does this PR introduce?

Description

Fixes an annoying bug where CodeMirror 6 loses focus completely a few seconds after the user stops typing inside a note.

Cause

The refreshVisibleSearch(false) or content.value mutation called asynchronously inside CodeMirror's updateListener triggers a reactive update/re-mount of the view elements, ripping the active selection and focus away from document.activeElement while the user is inside the editor.

Solution

Added an update.view.hasFocus validation to prevent the update listener from executing destructive reactive side effects while the editor view is actively focused by the user.
