TagSet copies no longer pull through from the mutable template; they copy existing tags and only use the template’s fallback (the HTML defaults) for lazy lookups. This keeps parser/session tagsets independent and prevents cross-thread mutation that can lead to ConcurrentModificationException.
This keeps the use of the HTML default tagset sparse in memory.
