Drupal.behaviors.xbDisableLinks doesn't disable links added to the DOM later

I think I hit this with a "simpler" scenario. I have a button link component within the slot of a another component. The page is then visited within the iframe. The problem does not occur if the button link is on its own and not in a slot.

Oh, and this effects anything using dynamic code components – menus for example.

Unassigning as I'm not working on this right now, in case anyone would pick it up.

I've got a MutationObserver working, making MR shortly

Closed 🐛 The navigation prevention inside the preview doesn't always work for code components Active as a duplicate of this. That one was tagged as a stable blocker, so transferring that tag to here.

I approved MR 1371 - it's a solid approach that doesn't require DOM vigilance. It's also more comprehensive as it covers keyboard interaction and submits. However, the issue is NR as this expanded functionality should probably get some e2e representation. You should be able to use the Cypress jQuery functionality to add a link to the preview iframe after it loads which would reproduce the scenario this fixes without having to deal with making a component do it.
jQuery('iframe[title="Page preview"]').contents().find("body").append(YOUR LINK[s] )

Tested new patch, works great

Test, written in Playwright, has been added now. I took the opportunity to also migrate all but one of the tests in ui/tests/e2e/preview.cy.js. The remaining test is a bit more tricky so I've not attempted to migrate that here. I've renamed the file to ui/tests/e2e/vh-units.cy.js because it now specifically tests that one thing.

The solution I was already happy with, and the new tests look good 👍,.
