Superscript/Subscript Buttons Should Handle Spaces

[cjc343]

Requirements

• This is a bug report, and if not, please post to https://lemmy.ml/c/lemmy_support instead.
• Please check to see if this issue already exists.
• It's a single bug. Do not report multiple bugs in one issue.
• It's a frontend issue, not a backend issue; Otherwise please create an issue on the backend repo instead.

Summary

When you select a sentence and press the superscript or subscript buttons, it creates markdown like:

^A sentence with spaces^ or ~A sentence with spaces~

These do not render properly. Instead, spaces should be handled either by escaping them (preferable IMO):

^A\ sentence\ with\ spaces^

Or skipping them:

^A^ ^sentence^ ^with^ ^spaces^

Steps to Reproduce

1. Start writing a post/comment
2. Select text with a space included
3. Press either the superscript or subscript button in the formatting panel

Technical Details

Not relevant, this issue occurs regardless of device or browser because the generated HTML does not format the text as desired.

Yep, we should add escapes according to pandoc, which markdown-it-sub and sup follows.
