Formatting is lost when backspacing on new line

[changyeamoon]

Describe the bug Formatting is lost when backspacing on new line

To Reproduce

GIVEN we are editing in the RTE AND we select a different format (font, font-size, etc)
AND we start typing, adding some content WHEN we break a new line
AND we start typing again
BUT we backspace back to the beginning of the new line THEN the text breaks format and goes back to default.

Expected behavior THEN the text format should stay consistent with last used format
