(this one is really bad, It needs and LRM to get the requested visual).

In general the problems are with numbers and punctuations expressions.
One problem is that the bidi algorithm change their order (not in the
way the user expects it). The other problem is the case where numbers
are moved to be on the right of strong L character.
