Documentation request: cannot chain .inputField

[jawspeak]

Worked around a bug which ideally can error if someone else uses it incorrectly as I did. Or at least the docs add this for inputField https://github.com/cronvel/terminal-kit/blob/master/doc/high-level.md#ref.inputField

This doesn't work

term.green.bold.inputField( //...

It fails ambiguously with

TypeError: Cannot read properties of undefined (reading 'removeListener')

stacktrace: TypeError: Cannot read properties of undefined (reading 'removeListener')
    at notChainable.grabInput (/<workdir>/node_modules/terminal-kit/lib/Terminal.js:1341:13)
    at Terminal.inputField (/<workdir>/node_modules/terminal-kit/lib/inputField.js:151:32)

But this does work:

term.inputField( //...

The source is pretty clear in Terminal.js this is not chainable, but it would be nice to enforce that with an error or at least docs.

notChainable.grabInput = function( options , safe ) {
	// RESET
	this.mouseButton( false ) ;
	this.mouseDrag( false ) ;
	this.mouseMotion( false ) ;
	//this.mouseSGR( false ) ;
	this.focusEvent( false ) ;
	console.log('TEST grabInput() this.stdin', this.stdin); // this is not defined if chained term.
	this.stdin.removeListener( 'data' , this.onStdin ) ;
