Settings Tray does not close on placement of block

I agree, this is a bit confusing. I guess on one hand it could be useful to have it stay open like it does, but it's I think it's more likely that the user is adding just one block

Agreed! Remaining open also impacts the perceived preview of visual layout by squishing things unnecessarily. It's already possible that the Preview might be slightly different from completely saving the layout, and this issue just adds another thing getting in the way.

Added a merge request with a 1 line fix. When the iframe modal is closed, the settings tray will also be closed. I think it's also reasonable to close the settings tray as soon as the iframe modal is opened, but that's more complicated I think. This also allows someone to close the iframe modal and make another selection from the settings tray if they want (like if they clicked the wrong thing).

I also first tried just configuring the module to have the iframe modal used for the remaining settings tray routes (choose block and choose section), but when I did that, things got a bit wacky after saving the block or section settings form. It reloaded the whole site inside the iframe.

I agree, after the user action is completed, the tray should close.

The proposed change in the MR addresses the problem.

Setting to tested as per #7

The changes from the merge request fixed the issue in Drupal Version 9.5.10 and layout_builder_iframe_modal 1.3.0.
Can this be merged into the next stable release?
Thank you

I downloaded this MR as a patch and it works as expected! Thank you for this fix.

D10 settings tray has a different CSS ID, added it as well.

Attaching static patch file for composer patching.
