Comment (by aduth):

 This can be demonstrated in the Gutenberg editor, which uses inline mode
 for rendering TinyMCE, including the Classic Text block. The related issue
 has been reported here:

 https://github.com/WordPress/gutenberg/issues/3568

 The above patch changes the behavior to retrieve `clientWidth` from the
 body element, which supports both iframe and inline modes, and should
 recreate the expected behavior of assigning an embed maximum width
 corresponding to the available width of the editor body.
