I've had a near continuos clone of this problem with the only wireless keyboard I'll allow in the same room as a swarf throwing metal carving machine. A logitech K-360. The problem can be solved on an rpi3 by calling up raspi-config as soon as its rebooted, and resetting the keyboard repeat. Most versions of linux gui's have a similar function if you can find it. Big IF. So IMO its something in the boot that does not properly set this, or maybe its set before the keyboard is found. Wireless keyboards (bt stuffs) and mice are way late found according to dmesg. Once set, its good to the next power bump that reboots it. Key shape (square sided keys) is what makes the logitech k-360 king in the shop, 99% of all keyboards have a straight walled mask around the tapered keytop. A bit of swarf falls into that tapered gap, follows the key down, and then wedges it in the down position. If that stuck key is in charge of moving the machine, all hell breaks loose because you didn't stop it by removing your finger. This is the major reason the high priced controls are all touch screen.
