I believe this is a regression in v18.5.27.1609, because I don't remember encountering this issue until the last couple days.
Given I am reviewing a Pull Request
When I click a line to add a code comment
And I type Shift-Enter
Then it should create a newline
And it should not submit the comment

I haven't had time to look at the source for what might have changed to cause this, but may be able to in a few days unless someone has an immediate idea of what went awry. As of now, this is forcing me to disable the plugin because I use that feature frequently and this is an annoyance.
Oh, that looks like it's a _feature_ - it's in the More Shortcuts section of the README. Is there a way to easily turn that off without having to manually edit the source code?
That's correct @supremebeing7 it's a feature. I'm unsure about whether there's a way to turn it off. Others will have to chime in.
Looks like you can disable by filename. I added add-keyboard-shortcuts-to-comment-fields
to the UI
That disables all of the other keyboard shortcuts on comment fields but I can live with that.
So, I guess we can close this.
Side note: It might be nice to have a better UI around disabling features.
