The sticky table library adds an extra table that does not pass accessibility validation.
The error that is returned is "Data tables must have unique names".

Changing line 101 in "core/misc/tableheader.js.
From:
this.$stickyTable = $('<table class="sticky-header"/>').css({
to:
this.$stickyTable = $('<table class="sticky-header" role="presentation"/>').css({
Will fix the issue.

I would post a patch but am in the middle of a project.
For those who want to fix it without altering core, you can make use of libraries-extend: core/drupal.tableheader to load your own js to override the Drupal.TableHeader.prototype.createSticky function.

Edit:
I now get another error with the above applied.
"Layout tables cannot have data table elements and/or attributes".
Maybe aria-hidden is called for?... I'm not sure yet

New developments and disruptive changes should now be targeted for the 11.x branch, which currently accepts only minor-version allowed changes.
