Issues with 'remove' command example and causes internal error

[MeemeeLab]

In the documentation of the remove command (https://hyperscript.org/commands/remove/), there is an example:

<button _="on click remove [disabled]">Un-Disable Me!</button>

I belive there is multiple errors in this example and does not work, because:
A. Correct expression for attribute is @disabled, not [disabled]
B. Disabled button does not fire on click
C. Button is not disabled in first place!

Another issue arises when using from along with this incorrect square bracket attribute expression (e.g., on click remove [disabled] from #box). It fails to execute with the error that is probably should not happen: Cannot read properties of undefined (reading 'parentElement')

I'm a bit of a noob at hyperscript, so I apologize if I've missed something.
