SpellCheck during Search&Replace-Popup: Applying results moves the focus to the segment

When a Search&Replace Popup is opened and focused and the spellCheck-Result is applied in the segment, the focus then jumps to the segment (= typing a search-term results in editing the Segment).
Opening the Search&Replace-Popup already terminates a running SpellCheck-process, but as soon as the user starts typing - also in the Popup - the SpellCheck-Timer starts again.
