unexpected/invalid role=presentation

[pkra]

Some examples

• $\iota :{\mathcal{C}}\rightarrow {{\mathcal{C}}one}({\mathcal{C}})$
• $b:{\mathcal{C}}\rightarrow {{\mathcal{C}}yl}({\mathcal{C}})$
• $\rho \mapsto (0\oplus 0 \oplus \rho )$
• $\varphi \circ \psi :{{\mathcal{C}}yl}(f)\rightarrow {{\mathcal{C}}yl}(f)$

These cases create some nodes without speech or braille but tree markup ending up with something like data-owns-id="12" aria-level="5" aria-posinset="3" aria-setsize="3" role="presentation" (which leads to validation errors since presentation does not support these attributes).

At least some of the cases seem connected to invisible times.

As an aside: svg-aam does not permit any roles on defs elements (so we should not set role to presentation).

The case of $\rho \mapsto (0\oplus 0 \oplus \rho )$ seems to be ok with SRE v4.

Fix solves the most problematic part but still seems weird.

Ok, the highlighting issue is my fault -- my demo wasn't styling the new .is-highlight class that aria-tree-walker uses.

It's still not great because SRE creates slightly weird markup (see my comment on the issue) which means the outline won't extend to all children. But that's a general problem.

Closing as essentially fixed.
