Nice! Very slick.
I was disappointed that Excel doesn't let us paste to a merged cell and also pastes results containing a break into successive rows below the "target" cell though, as that meant it simply doesn't work for me. I tried a few tweaks (unmerge/remerge, etc.) but then Excel dropped anything below a break, so that was a dead end.
Ultimately, I came up with a routine that'll handle simple tags and not use the "native" Unicode converter that is causing the issue with merged fields. Hope others find this useful:
Public Sub AddHTMLFormattedText(rngA As Range, strHTML As String, Optional blnShowBadHTMLWarning As Boolean = False)
' Adds converts text formatted with basic HTML tags to formatted text in an Excel cell
' NOTE: Font Sizes not handled perfectly per HTML standard, but I find this method more useful!

Note this doesn't care about tag nesting, instead only requiring a close tag for every open tag, and assuming the close tag nearest the opening tag applies to the opening tag. Properly nested tags will work fine, while improperly nested tags will not be rejected and may or may not work.
