 When resizing a Media and Text block, something like `style="grid-
 template-columns:9% auto"` is added to the rendered markup. If you're not
 admin (don't have unfiltered_html?), this is stripped by saving (in
 `safecss_filter_attr`, I think), which then causes the block to not match
 and appear "invalid".

 This can also be reproduced with plain content, using the HTML block:

 1. Use an "author" level user
 2. Add an HTML block
 3. Add the content  `<div style="grid-template-columns:9%
 auto">Testing</div>`
 4. Save the post and reload the page
 5. The style attribute has been stripped
