Steps to reproduce:
# Go to an arbitrary page on Czech Wikipedia.
# Open visual editor.
# "Insert" > "Template" > Input "Poznámka pod čarou" > "Add template"
# Fill the suggested parameter with arbitrary text.
# Click "Insert".
Instead of inserting the template, the editor gets stuck.
The content of the [[ https://cs.wikipedia.org/wiki/%C5%A0ablona:Pozn%C3%A1mka_pod_%C4%8Darou | template ]] is `{{#tag:ref|{{{1}}}|group="P"}}`.
