Test file showing the broken behaviour
Writer seems to always consider the point of text direction change (i.e. from RTL to LTR) a valide break point, even if it isn’t otherwise. In the attached file the first paragraph is broken after the opening parenthesis (end of RTL run) because it is follwed by digits (start of a LTR run). Replacing the digits with Arabic letter in the the second paragraph prevents the unwanted break point, as expected.

On Linux, I confirmed with 4.3 and 4.5, but not on 3.3 or 3.5. Thus marking as a regression.

Was able to replicate the issue but not find a bibisect version where it worked. Tested back to 3.5, location set to en_US.
