Review comments at @packages/react-core/src/components/Tabs/Tab.tsx:
- Line 108: Update the onClick handling in the Tab component so spreading props
cannot replace preventedEvents.onClick for a disabled custom link. Compose the
caller’s onClick with the tab handler, and ensure the caller handler does not
run when isDisabled is true.
Review comments at @packages/react-core/src/components/Tabs/TabButton.tsx:
- Line 32: Update TabButton’s type handling so custom components that render
buttons receive type="button" by default, preventing form submission; do not add
this prop to custom links. If the component type cannot be distinguished,
require callers to provide the button type and document that requirement.
Review comments at
@packages/react-integration/cypress/integration/tabsrouter.spec.ts:
- Around line 9-22: Replace the Chrome DevTools Protocol calls in the
`pressEnter` helper with a keyboard-event method supported by the declared
Cypress version across browsers, or use a Firefox-specific implementation while
preserving the Enter key-down and key-up behavior.

Looks good to me! I had a couple of comments, but I don't care if we address them.
| /** URL associated with the Tab. A Tab with an href will render as an <a> instead of a <button> unless component is supplied. */ | ||
| href?: string; | ||
| /** Sets the element or custom component used for this Tab's button or link. Defaults to an anchor when href is supplied, otherwise a button. Does not change the Tabs container's outer wrapper. Custom components must forward the ref and supplied props to the underlying element. For custom components that render a button, pass type="button" or set it inside the component to prevent form submission. */ | ||

According to this, ElementType should contain ComponentType, but I am also fine with this as-is. https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react/index.d.ts#L109

I don't think we ever reach the default now since Tab sets a component. I'm totally ok with leaving this if we think people use TabButton separately. It looks exported.
