If the filter allowed tags is checked everything is stripped except the allowed tags. It should skip to filter this part of the content, no?
Fixed this by modifying 2 lines in tree.js:
12: $(once('taxonomy-manager-tree', '#' + treeSettings[i].id)).each(function () {
and
$(once('input', '.ui-autocomplete'), once('input', context)).on('click', function (e) {
based on this:

and changing the dependencies in
- core/jquery.once to -core/once
It worth analyzing and creating a patch to be included in the next versions.
