Emoji superscript can still be split onto a separate line

[bmish]

I partially fixed this in: #203

In this example, the column width is so narrow that it linebreaks both emojis from their superscripts.

Solutions that didn't work:

• Turns out GitHub markdown filters out CSS styles so the previous solution doesn't work. There's also a GitHub pre-existing nowrap class but we can't add classes either.
• Of the allowed HTML elements, none that I tested helped us avoid the linebreak. <wbr> did not help.
•   in various placements did not help. It might have been more helpful if we could do something like ☑️ ⌨️<sup>&nbsp;🚫</sup>, but GitHub converts all emojis to a <g-emoji> tag for compatibility which prevents this from working. <code> and <pre> prevent the conversion to <g-emoji> but add unwanted formatting.
• There's no actual superscript version of an emoji character that might be more likely to stay attached to its base character, so I have to use the <sup> tag.
• Using <div> around the emoji (or <br> in front) and 5   in header appears to work but causes unwanted vertical spacing in header cell. Could avoid this vertical spacing if we could prevent the header conversion to <g-emoji>.
• Tried 0 and 1 superscript characters instead of <sup> with emojis but superscript still got detached

I may have to switch to separate columns for warn/off configs and avoid using superscripts in table cells due to the possibility of superscript detachment.
