If I understand W3C correctly [1], every space at beginning of line in (X)HTML should be removed. Currently Gecko doesn't do that and creates some space for text.

Reproducible: Always

Attachment: Bug minimal test-case

Space in line 20 (before <p>) causes additional space.

I do not think Gecko is wrong here. The first character on line 20 is a 'ZERO WIDTH NO-BREAK SPACE' (U+FEFF) / BOM. This shouldn't be removed, according to the specification you cite.
