HTML RawBlock isn't always verbatim copy of original HTML

[gpoore]

Under at least some conditions with invalid HTML in markdown, it's possible to create raw blocks that don't reflect the original HTML verbatim. The particular case I've found only involves an added space in a tag, which doesn't affect the output, but I'm opening an issue in case this same sort of modification might be triggered in another context where it would matter.

In temp.txt (note the error in the second tag):

<hr/></hr/>

Then (note the space in the first tag):

pandoc -f markdown -t native temp.txt
[RawBlock (Format "html") "<hr />"
,RawBlock (Format "html") "</hr/>"]

I've tested this under pandoc 2.5 and 2.6. It doesn't seem to matter whether the tags are on the same line or whether there is intervening text.
