Navigation keys doesn't work anymore into chat input message

[SilverYoCha]

Describe the bug
Sometimes, but often after trying to edit a previous message, navigation keys into input message do not work anymore.
It is no more possible to use left key, for example, to position the cursor one letter before.

To Reproduce
It is been a while that I try to identify a reproductible case, but without success.
Has anyone ever got this behavior?

Expected behavior
Navigation keys always usable.

Environment (please complete the following information):

• Desktop
• Browser all common WEB browsers
• Since Converse.js v7 (I don't know for previous versions)

Additional context
ConverseJS is used in overlayed mode.

Has anyone ever got this behavior?

I can confirm it. It is difficult to reproduce, but I get a fairly consistent hit after using an emoji. I am yet to confirm if it happens when no external plugins are activated.

I finally found a reproductible case.

• write and send a message (it is just at least to have one)
• open emojis drop down
• select one by using navigation keys
• close emojis drop down by using escape key
• try to modify previous message by using navigational keys
