I seem to be experiencing a bug with comment text. In some comments, usually at the beginning/end of sentences, the text will overlap. Making the end of one sentence lay on top of the beginning of the next. Somewhat demonstrated here:
(I'll add a better example if I can find one today)
After inspecting the source for the comments where this occurs I usually find a sentence that has more than one space after a period. This space coincides with where the over lapping text is. Removing the space fixes the over lap. Has this been previously documented?
