See the reference glyph for U+FB4B. One form looks like this with the
dot above further to the left, the other like it with the dot a little
further to the right. This glyph with the centred dot is a compromise
between the two.

I think that someday is today! Some Hebrew vowel marks are attached to
the consonant which logically follows. This applies in several cases in
Hebrew orthography, holam above the right of holam and alef, holam
sometimes merging with a following shin dot, and furtive patah which is
encoded following the base character (always word final) but pronounced
before it.
One way round the problem, in this specific case and more generally, is
to treat the vowel marks as combined with the preceding base character
even if graphically they are displaced on to the following character.
(At least, in Hebrew they don't modify the shape of the following
character.)
