Comment (by mihai2u):

 @afercia

 The colspan attributes I removed were always dynamically populated by JS.
 The colSpanChange() function looks at elements with a "colspanchange"
 class from what I saw in the code and adds the colspan attribute and value
 automatically.
 The JS does not require the attribute to be present (with an empty or
 placeholder value), because the attribute gets created with the JS call to
 set the attribute to a particular value. I verified that the areas where
 the placeholder colspan was removed from HTML still function well with
 javascript populating the correct values according to which page / browser
 size the element appears on.

 Regarding your reference to #40610 - this offers the same patch in the
 same fashion as that ticket there - the removal of the same attribute.
 If you'd like me to remove it from this ticket and allow the patch to come
 through #40610 instead, just ask and I'll accommodate. Browser-based input
 attribute validation has always been sketchy at best.

 Looking forward to getting a checkmark on this ticket, standing by to
 further support it to completion.
