Help:Lint errors/misnested-tag

This linter category has been added to assist editors in fixing wikitext and templates that have instances of misnested tags. Linter will flag a warning for all the examples below. We are treating this as a warning currently. In Examples 1 and 2, the  tag (either in HTML or wikitext form) should be properly nested inside the tag. While the parsers fix this up right now, the output may not always be what the editors intended.

In Example 3, the tag should be closed and reopened on lines 2 and 3.

In Example 4, HTML5 semantics require the tag (and other formatting tags like, , , etc.) to be wrapped around individual elements. But, a tag can be wrapped around lists. But, this is a such a common usage on wikitext pages that we should probably treat this as special wikitext semantics and not expect editors to fix them up. We are flagging this here in case editors are wondering why it is showing up. We'll try to remove this output from Linter as we tweak it further.
