We shouldn't need to set role here as this gets applied at element internals level if the variant is not set to link, aka role should just be automatically set by the pf-button component itself.

Suggested change

role="button"

[Atharv-G-Kulkarni]

Thank you for your suggestion.
I have removed role="button" and pushed the changes.

pf-button has an API for adding the accessible label. We'd use label here instead of using the aria-label on the host.

Suggested change

	aria-label="Expand Button"
	label="Expand Button"

[Atharv-G-Kulkarni]

Thank you for your suggestion.
I have changed aria-label to label and pushed the changes.

So enacting the requested changes myself locally I think I opened a broader issue here. Because we are using button as an expander, and using aria-expanded on it we equally need a aria-controls which isn't currently being applied. Also due to the fact the element being opened#expansion is across shadow dom roots I'm going to assume we are going to run into cross root aria issues with that.

@adamjohnson when you get the chance lets review this together.

can the button's aria-controls reference be to the row on
