keys: `<C-a><C-b>` does not work in `insert` mode

#296

For clarity, binding the keys in insert mode does not work. In normal mode, it does work.

glide.keymaps.set("insert", "<C-a><C-b>", "tab_next"); // Doesn't work
glide.keymaps.set("normal", "<C-a><C-b>", "tab_next"); // Works

Ah I figured it out, this is bad logic around cancelling keymaps in insert mode:

glide/src/glide/browser/base/content/glide.d.ts

Line 1201 in 30bfd0a

mapping_timeout: number;

I will double check what vim does here, but I think it just doesn't make sense to have this timeout logic for keymaps that use modifiers other than shift.

In neovim, it looks like all mappings timeout at 1000ms.

'timeout' 'to'		boolean	(default on)
			global
	This option and 'timeoutlen' determine the behavior when part of a
	mapped key sequence has been received. For example, if <c-f> is
	pressed and 'timeout' is set, Nvim will wait 'timeoutlen' milliseconds
	for any key that can follow <c-f> in a mapping.

						*'timeoutlen'* *'tm'*
'timeoutlen' 'tm'	number	(default 1000)
			global
	Time in milliseconds to wait for a mapped sequence to complete.

(h :timeout)

This is also a timeout for terminal stuff, but this doesn't seem to be for user actions stuff as much as making sure the terminal has time to forward keystrokes.

'ttimeout'		boolean	(default on)
			global
	This option and 'ttimeoutlen' determine the behavior when part of a
	key code sequence has been received by the |TUI|.

	For example if <Esc> (the \x1b byte) is received and 'ttimeout' is
	set, Nvim waits 'ttimeoutlen' milliseconds for the terminal to
	complete a key code sequence. If no input arrives before the timeout,
	a single <Esc> is assumed. Many TUI cursor key codes start with <Esc>.

	On very slow systems this may fail, causing cursor keys not to work
	sometimes.  If you discover this problem you can ":set ttimeoutlen=9999".
	Nvim will wait for the next character to arrive after an <Esc>.

						*'ttimeoutlen'* *'ttm'*
'ttimeoutlen' 'ttm'	number	(default 50)
			global
	Time in milliseconds to wait for a key code sequence to complete. Also
	used for CTRL-\ CTRL-N and CTRL-\ CTRL-G when part of a command has
	been typed.
