I don't know about Tamil, but I suspect that this is a rendering issue
rather than a Unicode design bug.
In standard Tibetan orthography only a single vowel sign may be
attached to a consonant stack, but in non-standard orthography used
for shorthand contractions multiple vowels may be attached to the same
stack. For example the contraction bskyeeed བསྐྱེེེད <0F56 0F66 0F90
0FB1 0F7A 0F7A 0F7A 0F51> with three stacked /e/ vowel signs
represents bskyed bskyed bskyed བསྐྱེད་བསྐྱེད་བསྐྱེད (and I believe
that forms with four or more stacked vowel signs occur although I
haven't encountered any such examples yet). On my system this and some
other multi-vowel stacks such as kii ཀིི <0F40 0F72 0F72> render
incorrectly with a dotted circle before the last vowel sign. But I
take this to be a deficiency in the Tibetan fonts available to me
rather than a design flaw in the Unicode Tibetan model.
