"Enter to send" setting doesn't work reliably

[JKingweb]

Before you create a new issue:

- [x] I searched for similar issues and did not find one
- [x] I'm using the latest version available in the [Windows Store](https://www.microsoft.com/store/apps/9NW16X9JB5WV)

I'm submitting a...:

Bug report (I searched for similar issues and did not find one)

Current behavior:

Pressing enter doesn't always send messages when the option to do so is turned on. Pressing enter does, however, reliably send if one has previously pressed Shift+Enter to insert a line break during composition.

Expected behavior:

The setting should work reliably

Minimal reproduction of the problem with instructions:

1. Enable the "Enter to send" option
2. Type a short one-line message
3. Press enter to send the message
4. UWPX may instead insert a line break, or it may send the message (I have not been able to ascertain a pattern in its behaviour)

Environment

App Version(s):
v.0.19.0.0
