Warning

6fe6a76 is not a fix! It allows to spot where the issues raised by vnu-jar are located!

There seems to be two kinds of issues:

• The presence of the aria-labelledby attribute for the <div>s related to modals and offcanvases
• The presence of the role="tab" without any aria-controls (or any other modifications)

I'm not sure yet if these are false positives and would need to be hidden, or if we'd need to modify some examples/usages.

thought i was having deja-vu ...

twbs/icons#2221

my fix for the offcanvas there twbs/icons#2222

[patrickhlauke]

for offcanvas (and presumably modal is the same), we should have an appropriate role (like "region") even when they're not shown. additionally, we should change the JS to store the current value of role before turning the thing into an actual modal/offcanvas...and once it's closed, restore the original role (rather than just removing the attribute altogether)
