oh, that would be helpful! 😄 I can't find anything specific in the webkit bug tracker, and there are just a few vague references to it on the odd stack overflow post.
Yep, me too. I have 🤞 that there is an alternative to the retry, but haven't had much luck trying to find one so far. I can't see that we are doing something obviously wrong here. In Safari's case it is like we need an onload listener on node.contentDocument instead, or using |

@glendaviesnz We shouldn't check the iframe body because we actually remove that ourselves. That's because we render the body with React and need to avoid two body elements. So we should remove all this logic introduced last week here because it's not possible to have initial body classes: If you remove that logic, it will fix the error, and your issue. |

What?
Often in Safari the correct styles are not applied to the editor iframe elements. This currently only shows itself in zoomed out mode as the
.block-editor-iframe__htmlclass is not applied, so the required transformation styles to make zoomed out mode work are not applied.You might need to refresh the browser several times to see the issue, it does not happen with every load.
Why?
Sometimes Safari fires the load event before
contentDocumentis properly loaded in the iFrame, so acontentDocument.bodyis null exception is thrown and the correct classes are not applied.How?
Checks that
contentDocument.body !== nulland if it is runonLoadagain after a timeout.Testing Instructions
