Preessing Enter key with physical keyboard on Android inserts a linebreak and then sends the message

It ends up creating extra line breaks in a message if the cursor isnt at the end of the message.

How to reproduce:

1. Connect physical keyboard to device.
2. Type any message, e.g. "testing"
3. Move text cursor to the left, e.g. so it looks like "test|ing"
4. Press enter

Instead of sending the message "testing", it will send a message consisting of two lines that looks like this:

test
ing
