Fix: update other radios tracked value in one group when one is updated to be checked

[zhengjitf]

Summary

Fix #26876, which is caused by not updating tracked values. Please see here for the investigation details.

The root is, when one radio is changed to be checked (by updating the checked prop), the previously checked one won't update its tracked value (will be still 'true') if it's one of the previous siblings.

How did you test this change?

Testing Steps (refer to but not exactly follow the steps of reproduction):

• Two radios with the same name, initially, radio1 is checked, and radio2 is unchecked. (radio1 is the previous sibling of radio2)
• Update the checked props to make radio1 unchecked, and radio2 checked.
• Then update the checked props to make radio1 checked, and radio2 unchecked.
• Click radio2, the onChange handler should be called after fixing the issue.

Any feedback and suggestions will be appreciated. cc @eps1lon @sebmarkbage @acdlite

This is going to be a fragile fix due to it querying the DOM during the mutation where things can happen before or after depending on tree order. It would also potentially trigger thrashing of the DOM internal caches instead of all writes and then reads.

If this worked before I think the solution is probably more likely something about the timing of when the mutation should happen to replicate the previous order of operations.
