Email editor scrolls when <Ctrl><Arrow> is used

This bug was mentioned before, a movieclip was made and shared, but it still happens all the time.

Windows-10, emclient 8.2.1509 (b0e58cf)

When editing an emailbody and I use keycombinatie or , then the emailbody scrolls down, so the text where the cursor stands, is not visible.

This still hapens after a lot of updates. When will this be solved?
