"comment" in unlikely candidates mutilates formatted code blocks

[abeyerpath]

I've seen several cases of code blocks using color schemes where "comment" becomes a style and starts getting trimmed. At best this loses all the comments, and may further mutilate the structure.

I wonder if the unlikely candidates trimming should ignore elements inside of pre/code blocks?

Then it wouldn't cut ads and different "related" blocks that didn't get below the cut threshold.
Could you please provide an (or several) example page(s)?
