VideoPress: Fix issue with VideoPress block with 0 height and width

[dhasilva]

Fixes #41317

Proposed changes:

• Removes the flex display of the video wrapper, going back do block. The element contains only one child, so in theory there should be no problem

The script that adjusts the iframe seems to fail when the display is set to flex for some reason. My guess is that there is some race condition or browser bug involved, so this seems the simplest way to solve it.

Testing instructions:

• On trunk (Bleeding Edge with Jetpack Beta), go to the block editor and add a VideoPress blog.
• Upload one video, save and publish the page.
• On the published page, check that the video is displayed as expected on the default theme and other block themes
• Check that the video is NOT displayed on some classic themes such as Shoreditch, Kadence and Twenty Nineteen
• Checkout this branch
• Visit the published page again or reload it
• Check that that the video is visible on all listed themes (bonus points for trying other themes 👍 )
• Now do a quick test with the VideoPress plugin instead of Jetpack, by checking out this branch on VideoPress and removing the Jetpack plugin
• Test also on a simple site

Nice work! Videos display correctly in old themes now. I also swapped back to the 2025 theme and it still looks correct.
