Pressing backspace and space on Chrome at the beginning of a line wraps words wrongly

[Fabrizio Bettinelli]

Steps to reproduce

1. Create a paragraph with more than two lines
2. Put the cursor at the beginning of the first word of the second line (or any after the first line).
3. Press backspace and then space.

Expected result

The word goes back to the upper line.

Actual result

Both words stay on the current line.

Other details

Tested on the current latest version (4.5.10). It can only be reproduced on Chrome, and after generating the issue, if changes are saved, you can also see the wrapping issue on other browsers.
