tinyMCE editor breaks captions with HTML

[iantresman]

This looks similar to ticket #18311

If I enter HTML into an image caption (eg. <ul> <span> <div> <table>, and then in tinyMCE I switch from Text to Visual, my caption breaks; sometimes it is reformmatted, sometimes the caption shortcode is removed.

Test caption:
<table>
<tr><td>Label</td><td>Description</td></tr>
<tr><td><span>Text</span></td><td>More text</td></tr>
</table>

Hi @iantresman, thanks for reporting this!

Not sure what the ideal behaviour here should be, and from the ticket you linked it seems the question has a long history, so requesting a second opinion for this.
