This library was about to be updated in #39752, but blocked by an issue mentioned here. See the issue: jsx-eslint/eslint-plugin-jsx-a11y#959. Shouldn't the rule only apply to interactive elements, as per the docs? In that case, shouldn't it not fail for the th table header element?

[Janpot]

You are right, I acted too fast, thanks for catching it. Perhaps we can add th to the ignore list instead?

Perhaps we can add th to the ignore list instead?

Shouldn't th be ignored by ESLint by default? It's fine with me, but only if the package update is critical.

[Janpot]

No, it's not critical, I'll pin the dependency version so that we can proceed with the lockfile maintenance PR.

Looks good. Updated the PR title.
