@Gábor, I have looked into the breadcrumb issue and applying the display: inline-block; style to both LTR and RTL produces the expected result and is consistent with the design.

Similarly, I have checked the 14px -> 1remand it seems applying the 1rem value to the original style does not affect the design significantly (noticeably even); it only add 2 pixels more to the search results Header in LTR which is not aligned to anything else.
