Modal Does not Close Automatically (possibly only on multilingual sites)

Hi Mark,
Thanks for reporting. I have the 1.3.0 version as well and I can't reproduce the issue. Checking at the iframe src, I can see ?destination=/layout_builder_iframe_modal/redirect. When I submit, the modal is properly closed.

Which version of Drupal are you using?

We are on Drupal 10.0.5 and seeing the issue.

Hi @vbouchet, I have the same issue here. My project is drupal/core-recommended: 9.5.7. I use drupal/layout_builder_iframe_modal: 1.3.0. At the moment we faced this issue, after adding multilingual functionality via drupal core built-in multilingual functionality. Using language detection via URL by domain. Just as Mark mentioned I tried to change following: 'destination' => Url::fromRoute('layout_builder_iframe_modal.redirect')->toString(TRUE)->getGeneratedUrl(), back to 'destination' => '/layout_builder_iframe_modal/redirect', and it works fine in that case. When I work with iframe without multilingual changes everything works fine.

I can confirm that our site is multilingual as well.

Same issue here, also on a multilingual site. I've opened a branch with the fix. It doesn't seem to want to let me open an MR right this second, but I'm attaching a patch with the fix.

This fix basically just switches the generated URL to be relative. I'm not sure what the reason for the original change was so not sure this is an acceptable solution or if an absolute URL is actually needed. But it does solve the issue.
