Blocks: Improve Site Editor Support#2233
Merged
Conversation
The Site Editor previews all blocks in an iframe that's completely separate from the regular editor. This results in a disconnect between the available assets in and out of the iframe. This change copies over required assets, and WP templates for WB form fields to work as expected.
There's still some issues with the field in repeaters, but this is the bulk of the required changes.
The image importing functionality doesn't currently work. This is due to the field being inside of the iframe, and how WP handles that.
The clone process by WP doesn't always succeed. It's much more reliable if we do it ourselves.
Undo link doesn't work as expected.
This is a core admin class that's not found in the Site Editor Canvas.

This PR adds Widgets Block compatibility for the Site Editor. The Site Editor uses an iframe (known internally in WordPress as Canvas) to provide isolation to Blocks from admin styles. Unfortunately, none of the widget bundle fields were compatible by default and needed alterations to account for the Site editor canvas being inside an iframe.
This PR also adds end-to-end testing (e2e) through Playwright. Playwright test code found in the siteorigin/siteorigin-tests-common repo.
