I'm trying to add Templatedata to a portable infobox via the "Manage TemplateData" button in the source code editor, but upon hitting "Apply" the dialog just hangs and nothing happens. Clicking on "Cancel" does not work. I need to refresh the page but nothing is affected anyway.
TemplateData does seem to work fine with other non-infobox templates, as it applies the templatedata tag normally and the documentation is generated as it's expected.
PI: https://empireearth.fandom.com/es/wiki/Plantilla:Infobox_Edificio (TD is borken)
A regular template: https://empireearth.fandom.com/es/wiki/Plantilla:Icono (TD works)
Do portable infoboxes not get along with templatedata or am I missing something?
