Assessment

This issue has not been assessed yet.

Description

Currently, when .cssSelector returns empty results, the tagAppend*() family does nothing to warn you about it (it probably should?)

tagAppendChild(span(), .cssSelector = ".foo", 1)
<span></span>

Same goes for any function that has a .cssSelector argument
