I wouldn't call it a compensation. In fact, it was deliberately designed this
way all the way from the time boxes were first introduced.
It's not at all bad practice to treat presentation and semantics differently.
TagBox is deeply about semantics, and it allows you to link presentation aspects
to those semantics, which is all well and good...but any attempt to build a
semantic layer which depends upon parsing all of the available presentation
information with, at best, heuristics regarding the semantic utility of that
information is going to quickly end in a very frustrating mess.
