keyboard teleop not reading keyboard correctly

[Chambana]

OS: Ubuntu 22.04
ROS_DISTRO: ROS2 Humble
Arch: AMD64 / x86-64

When holding down the arrow keys, the input momentarily reads and publishes a 0.0 value. This occurs every time i hold down and arrow key and is reproducible on the version of keyboard teleop in this repo.
In this gif, I cycle through each arrow key and hold it down for several seconds. Notice that the output value momentarily goes to 0.0 and then recovers.
