Keyboard corruption with Caps Lock remapped to Ctrl

Hi,

Thanks for blink!

I have an iPad Pro 9.7 with the Apple keyboard for it. I want to use Caps Lock as Ctrl. So, in config -> Keyboard I have assigned Caps Lock to Ctrl.

When I attempt to use it, the behavior is pretty odd. Usually after doing that, the keyboard is unusable; further keypresses — even just typing plain text — may do nothing at all, or may send garbage, or may corrupt the terminal, or sometimes hang the terminal session. Command-T to open a new tab will be fine, and that tab will work normally (at least until I try to use Caps Lock as Ctrl in it), but the original one will remain hosed.
