Summary

When using the replaceText(String) method on a CodeArea the scrollbar jumps to line 2.
This happens when the replacement string is shorter or longer than the current text.

Expected Behavior

Scrollbar keeps in place when replacing the current text by a text with a different length.
This worked until richtextfx verions 0.9.2 (see video "scrollbar_doesnt_jump" in scrollbarjump_demo_and_videos.zip)

Actual Behavior

Scrollbar jumps to line 2 when replacing the current text by a text with a different length (see video "scrollbar_does_jump" in scrollbarjump_demo_and_videos.zip).

Reproducible Demo

See scrollbarjump_demo_and_videos.zip.

Press "Replace with long lorem ipsum" button.
Scroll to line 6 (doesnt matter which line but should be > 2)
Press "Replace with short lorem ipsum" button.
