Steps to reproduce:

Open a post edit field (new thread / answer) on a forum powered by simple machines ( and type an 'ß' (german sz).
Please note: Only Firefox Mobile shows this behaviour - no other browser, may it be chrome, opera, or any other.

Actual results:

As if the 'save' button had been pressed, the form is submitted.

Expected results:

A 'ß' should appear in the textarea element.
I can reproduce this issue, by trying to post a comment on a thread from (you need to create an account for this). 
With the keyboard set to German, tap the single letter 'ß' (from the autocomplete suggestions in my case).
Result: The edit form is dismissed and would be posted if the captcha is correct.

Keyboards used: Gboard & SwiftKey
Build: Nightly 57 (2017-22-08)

Some key events synthesized from strings can have modifier metastates.
For example, from the sharp S character, we synthesize an S key with Alt
metastate. However, we don't actually want to pass the Alt metastate to
Gecko because the Alt meta key is not actually pressed in this case.

If we couldn't reproduce it on beta 56, are you sure we should uplift this?

Sorry, I should have mentioned I was able to reproduce it on 56 Beta on my device.
