I mainly want to ask if this is the expected behavior, I don't see any related info in help files. But even if it is, personally I find it strange.

I use the leadmultispace to achieve the indentation ruler, and I noticed that in my own color scheme, those characters will not have the correct color in selection. It will use the highlight group of the first non-blank character in that line.
