In WYSIWYG editor, i tags with class but no content are removed.

[LiamKarlMitchell]

Summary (*)

These are used for icons to be shown in some blocks/content and so editing the content causes the icons to be removed.

It probably removes empty spans as well but I have not tried this yet.

Duplicate of #21602 which was closed for no reason.
magefan/module-wysiwyg-advanced#13

Preconditions

Magento 2.3.0
Magento 2.4-develop

Examples (*)

Steps to Reproduce

Edit a block or page content in the source edit.

<i class="icon-paperclip"></i>

Click show editor.
Click hide editor.

Actual Result

And its gone...

Expected Result

Tag is not removed

Another example

Test
<i class="footer-icon icon-line-clock"></i>
Test

Becomes

<p>Test Test</p>

You can hack around it with an html comment as content such as

<i class="icon-paperclip"><!-- icon --></i>

But then it gets changed into an em.

<em class="icon-paperclip"><!-- icon --></em>

Font awesome for example uses i tags.
In my case, WeltPixel Pearl theme uses i tags, especially their example content that is imported with the theme which we just want to edit/tweak as needed.

Proposed solution

Keep tags if they have no content when there are classes or attributes set.
Maybe this should only apply to some tags such as a, i, div, span?

Perhaps not p tags as TinyMCE if I recall litters them all over the place and the removal of empty elements was made to clean up such issues, best if can consider i and span tags as non empty when they have class.

@magento Confirmed on 2.4-develop

Entered in the content in source editor.

<p>CMS homepage content goes here.</p>
<p>Icon should be here: <i class="footer-icon icon-line-clock"></i></p>

Click the Show / Hide editor, wait a moment.

Click the Show / Hide editor again to go back to source editor.

Content lacks the "icon" element.

<p>CMS homepage content goes here.</p>
<p>Icon should be here:</p>

Issue: Confirmed

This is because somehow not an entirely recognized html tag by tinymce. And tinymce also remove an empty html tag because it's "empty".

At this moment I am using <em class="fa">&nbsp;</em> this should work just fine.

This an issue for me on 2.3.5p2
It is a common problem
might be useful
https://github.com/claviska/tinymce-iconfonts

Or perhaps

tinyMCE.init({
// ...
extended_valid_elements : '[]',
});

following last post i have installed the tinymce plugin mentioned above (tinymce-iconfonts) and it allows me to use e.g. font-awesome immediately. had to edit file to add plugin as per here - https://devdocs.magento.com/guides/v2.4/ui_comp_guide/components/wysiwyg/configure-tinymce-editor.html

added plugin to this file
/vendor/magento/module-cms/Model/Wysiwyg/DefaultConfigProvider.php
then uploaded the two files and deployed static content (finding location took some time, but hint on the tinymce page which shows the location it is expecting file)
