Bugfix 3.1.x: Use TinyMCE getContent() to get editor contents on save

[frapell]

@petschki So, apparently the fix I did here was lost because around that time it was the ES6 rewrite happening...

@petschki @thet If you guys could take a quick look :)

For master I submitted another PR #656

[petschki]

same simplification like in #656 ... good to merge

[petschki]

mosaic 3.1.x is for Plone 6.0.x / staticresources 2.1.x so mockup should stay on 5.1.x ... this is all because of the pat-contentbrowserpattern which was introduced in mockup 5.2.x

[petschki]

@thet I'll revert your version updates here and align it to Plone 6.0 pins as mentioned above ... currently I cannot debug anything due to the sass warnings ...

new changes

@petschki @thet I've tested with latest changes, and this still doesn't address the issue #486

You can test this by simply adding a RichText tile, then using the code tinymce plugin and enter this

<p>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" type="text/javascript"></script>
</p>

After saving, and then saving the Mosaic, if you inspect the HTML you will see

<p>
<script data-mce-src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" type="mce-text/javascript"></script>
</p>

All of those mce added are used by TinyMCE internally and the tile should not be saved like that.

@thet I've reverted the dependency version updates for now and my code improvement since it didn't worked reliable on 3.1.x

@frapell your initial fix is working for me now and I will not put any effort in code cleanup/refactorings for 3.1.x anymore. when you can confirm, I'll merge this.

[frapell]

@petschki Yup, this is now working fine for me... I think it can be merged (And if we can get a new 3.1.x release, that would be great :) )

FYI, I tried yarn install and yarn build and I still get differences, and the feature continue to work the same, so no idea what's going on there 🤷

[petschki]

I'll come up with some dependency version updates and pins for Plone 6.0 in a separate PR ... I'll merge this meanwhile

[petschki]

I've released 3.1.6 with this fix
