Title component inconsistent prop defaults #1439
Description
size prop is required without a default
headingLevel is not required, but has a default
We should align these two. headingLevel should be required as a default of h1 leads to non-semantic markup structures for users who go with defaults. It's not good for accessibility as it stands out of the box.
Further, we'd probably benefit from shortening the name from headingLevel to simply level.
