I don't understand this comment. I'm assuming you get some sort of namespace
collision that is too hard to clean up?

[Daniel Bratell, 2017/06/30 08:22:19]

Yes, HTMLObjectElement inherits from both ListedElement and HTMLElement. There
are different global templates with the name toHTMLInputElement that can handle
either type, and if both those sets of templates are visible at the same time,
the compiler doesn't know which template to expand.

The patch to rename/restructure it is too big to land without having a concrete
reason so I haven't even tried. Once this is in the tree I plan to change the
code so none of these exclusions are needed but I have a "chicken or egg"
problem.
