Allow editor stylesheet on frontend

[webmandesign]

Certain plugins use TinyMCE editor on frontend of the website. Such as ​Beaver Builder page builder.

When a theme uses an editor stylesheet, this is being loaded in WordPress admin only currently, which creates inconsistency in using editor on frontend.

Could the early exit admin check be removed from ​add_editor_style() function, or at least made filterable?

I've tried to submit a GitHub repo patch via ​https://rmccue.io/patch/ but I'm ​stuck at step 5 getting a JS error.

So, here is a patch reference: ​https://github.com/WordPress/WordPress/pull/213

Adding an editor stylesheet(s) is responsibility of the theme, right?

In that case a plugin using the TinyMCE editor on frontend doesn't know about what editor stylesheets the theme includes. So, using mce_css filter in plugin doesn't make sense really.

Likewise, if the theme wants its editor stylesheets to be frontend available, it should hook to mce_css right from the start. Then what point there is to use add_editor_style()?

​I've proposed the way which filters the ! is_admin() conditional inside add_editor_style(), so a theme can use add_editor_style() as usually, while a plugin which uses TinyMCE editor on frontend can hook onto the conditional and change it when needed so it allows theme editor stylesheets in frontend editor.

What do you think about that?

Hi @webmandesign, I'm not sure adding yet another filter is the best way to go. Also this is still a duplicate of #34882. Lets continue there.
