Firefox translate feature makes CTD feature comparison unreadable

[alexgibson]

Description

When i visit the CTD campaign page and let Firefox translate the page to English for me, it renders the feature comparison chart unreadable. My guess is this is because we're using <td class="firefox" aria-label="checkmark">✓</td> instead of something like a CSS image replacement technique.

Steps to reproduce

1. Open https://www.mozilla.org/de/firefox/
2. When Firefox asks if you want to translate the page to English, click Translate

Expected result

Actual result

Environment

Firefox Nightly
macOS

This looks like a bug in Firefox translations in general with any unicode/emoji glyphs:

I'll look into reporting the bug: https://bugzil.la/1914159, not sure if a workaround in bedrock is currently worth it? (Like changing the checkmarks to bullets perhaps?)
