Why remove the #if?
 #if ENABLE(PROGRESS_TAG)
862861         tagList.add(progressTag.localName().impl());
863  #endif

Since progress is added to the tag names, the HTML parser will not create a progress element for ports that don't support the progress flag, unless it is also added to the tag list. If added to the tag list, the parser will create a "regular" HTML element when the flag is turned off.
Please see ruby and datalist, they are also added to the taglist unconditionally.
However video is not, and in ports that don't enable the video flag, the HTML parser is not creating a video element at all.

I don't see any comment or test case about this change. What's the deal with this?

This change should not be included in this patch.  I'll revert it.
It fixes a bug that ':optional' CSS selector should not be applied to <button> and <progress>.
