…htmlFor matches control's id This change adds an option to the `label-has-associated-control` rule, enforcing that the label's htmlFor attribute matches the associated control's id attribute. Previously, the only validation done on htmlFor was that it was on the label component and had text. There was no attempt to cross-check that value against any attribute on the associated control. Not, when the option is enabled, cases where they don't match will report. I also took the opportunity to update the error messages so that each assert type gets an error message with verbiage specific to the assertion. (not sure if this should be called out as a separate feature in the changelog?). Note: the current implementation only checks the first instance it finds of child component that matches each control component type. It assumes that there won't be any acceptable cases where a label would have multiple inputs nested beneath it. Let me know if that assumption doesn't hold. Closes:

It would have been better to use Omit here to remove openingElement and closingElement from JSXElement, but this version of flow doesn't have Omit (that was introduced in 0.211.0). I'd be up for upgrading the version of flow in a separate change if you'd like?

The ast-types-flow package doesn't include a type for JSXFragment

@ljharb I realized this is still pending review. Is this feature still something you want to move forward with? |

Note: the current implementation only checks the first instance it finds of a child component that matches each control component type. It assumes that there won't be any acceptable cases where a label would have multiple inputs nested beneath it. Let me know if that assumption doesn't hold and i can refine that logic more.
