The bug I wrote about some time ago with invalid XSLT still exists in v.14.1
That time it was missing the <tbody> in a <table>. This time it was an <input> inside a <tr>. Obviously wrong, I know, but apparently whichever version it was written in back in 2010/2011 allowed it and today, when I wanted to do an edit, the editor crashed.
The <input> was moved to the <td> within the <tr>.
