Incorrect keyboard navigation in RTL mode

[Dumluregn]

Type of report

Bug

Provide detailed reproduction steps (if any)

1. Go to CDN
2. Set RTL text direction for the first paragraph

Scenario 1:
3. Place caret at the end of line (after world)
4. Press right arrow

Expected result

Caret moved left (that's default in RTL)

Actual result

Caret is stuck in the same place

Scenario 2:
3. Place caret in the middle of line (e.g. between words)
4. Try to navigate to the ! using right arrow

Expected result

Navigation is intuitive and caret moved character by character.

Actual result

When caret is between letters H and e and right arrow is pressed, caret is moved to the end (beginning) of the line.

Other details

It looks similar as #2104, which however turned out to be an upstream issue.

It seems to be Chrome's bug as it's reproducible also without CKEditor 4 instance: https://jsfiddle.net/Comandeer/mn8h76tw/

Confirmed - Chrome and Edge are broken. I'm reporting an issue in Chromium tracker.
