I have a strange behavior with my Google Keyboard on a Motorola Moto E (2nd Generation, LTE) with Android 6.0. Occasionally pressing the backspace key will result in adding word fragments. In the following GIF I only press the backspace button from frame to frame. This is really annoying because I try to just delete the last word and then have to cycle through this.
Is there somewhere I could file this bug? Is there any hope that this would be eventually fixed for my phone?
