Bug with inputs

Hi there! I created my own block tool for Editor. In my tool you have to input some text, then click "save" button, then it will render. So everything is ok, besides input. When I press Enter on the keyboard when input is focused - it creates a new block with this input. Maybe it's my bad, maybe its a bug in Editor. I have the same issues with every input in my custom block tools. Here is the video https://recordit.co/bvGKcGuRav
