Modal window causes the entity browser iFrame to be loaded twice

My project has a custom (entity browser) test that was (sometimes) generating the following PHP warning:

I digged a little further in what's causing this and I found out the entity browser iFrame is actually loaded twice. The first load is quickly aborted (results in a 499 in Nginx), after which the same request is launched again:

The entity browser URL is opened through an iFrame. The way (AJAX) dialogs in Drupal seem to work is that the HTML received through the AJAX-request is first added to the <body>-element (see ), after which jQuery dialog functionality kicks in (see https://git.drupalcode.org/project/drupal/-/blob/11.x/core/misc/dialog/d...) which first removes it from the -element - stopping the iFrame from loading (= browser aborts the ongoing request). The AJAX response content (containing the entity browser iFrame) is then added again to the <body>-element, (wrapped with dialog-specific HTML elements), which makes the iFrame start loading again.

Although not that of a big deal, I'm wondering if this is something that can be improved upon?
