TypeError in no-unsupported-elements-use-aria

[erin-doyle]

When using rule: no-unsupported-elements-use-aria I am getting the following error:

Uncaught (in promise) TypeError: Cannot read property 'reserved' of undefined

The error is occurring when the tag it's testing is a <g> tag which is a child of an <svg> tag. The code that is blowing up is here:

const reserved = DOM[tagName].reserved || false

It seems that the <g> tag is not found in the DOM object. I think maybe there needs to be a try/catch of check on existence before checking for reserved. There are apparently a lot of possible children tags of <svg> elements, so it seems this could come up more often.
