<tr style="display: none;"> does not work
When applied via a class, or style, the above does not hide the table line as expected. This works in IE as expected.
Setting
<tr style="visibility: collapse">
Hides the row, but the table then has a "Gap" where the rows are supposed to be.
Again, works as expected in IE 11
This library base implementation (probably was long before Arthur began committing to it) is really hacky, it is nowhere near how a real HTML renderer should work or be implemented. So don't count on uncommon use cases like this to work, better to just delete them entirely from your HTML source by a RegEx or something.
But it's very good that you submitted the ticket, of course - thanks for this 👍
