The text displaying the quote source doesn't scale down with the quote, so it clips the box after multiple quotes. Like I mentioned yesterday, it's a minor issue.
The very last one in the chain features scrollbars as well (attachment).
The scrollbars are (I think) due to the smiley... not much I can do about that one.
The quote headers should scale along with their contents now. They'll be a bit larger than they used to due to this, but it's not a big deal.
Technical explanation:
Quote headers were set to "x-small" font-size, which is not relative. Blockquotes were set to "0.9em" font-size, which
is relative to the parent container's font-size. Hence the ever-decreasing font-sizes in ludicrously-nested blockquotes.
The fix to get the quote headers to scale down as well is to convert them also into EM-based sizing. With the current forum font-size, "0.8em" resulted in near-identical sizing to "x-small", however this also meant that the quote headers were shrinking in size twice as fast as the blockquote contents ("0.8em" vs "0.9em"). So I settled for "0.9em" sizing, resulting in headers that are larger than they used to be, but which will scale down at the same rate as the contents they belong to.
