I think the issue here is that radio buttons are considered individually focusable by findTabbable(), but the browser treats a group of radio as a single focusable item when tabbing, if their name attribute matches.

I've also noticed that if you hold your mouse down on a radio button then focus is shifted back to .ReactModal__Content. When you release the mouse, focus is then returned to the input.

I'm not sure if this a related or separate issue.

We ran into a similar issue. Here are some details.

Our modal contains a bunch of fieldsets. Each fieldset has several radio buttons.
In the footer of the modal is submit button that is disabled.

When you press tab on chrome, it only cycles through just the first radio button within each fieldset. Whereas on Safari, it goes to each radio button for each fieldset.

As a result, when we press tab to reach the first radio of the last fieldset, and then press tab again, it does not cycle to the modal close button because the first option of the last fieldset is not the tail element in the list of tabbable elements. Here's where the logic fails.

Hello, I don't mean to necro this, but has anyone found a workaround for this issue? I noticed that this issue is still open and I, too, am experiencing this issue :(

🧟 Bringing this back form the dead has there been any work on finding a solution?
The way this is currently handled looks to need enhancement to check for type=radio and then walk for all matching name fields.

The current solution is clearly a WCAG violation as it breaks navigation for keyboard users, at minimum the documentation should be updated to highlight this.

@stephenmcm @coulgreer @ryansukale The issue is still open. It's up for grabs - PRs are welcome.

Hey @diasbruno, I'm going to take another look into this one. 👀 Will update once I have more information!

@doeg Awesome. Let me know if you need anything.
