Plugins iframe blank after Library re-render when opened immediately #719
Description
The plugin iframe loaded by the DA Library renders a blank document when immediately clicked after opening the Library.
If you open a plugin quickly, before all blocks, icons, etc. are loaded, the src attribute is removed from the plugin iframe. Note that the data-src attribute remains set to the correct URL. This issue occurs more frequently as a library grows with more content.
This happens due to a re-rendering triggered after all other library items have loaded and results in a cleared iframe with empty DOM. Navigating backwards in the Library and re-opening the selected plugin resolves the issue because the content loading has already completed.
