Xterm.js in headless mode yields TypeError on resize

[johnpoth]

When running Xterm.js 3.0.2 in headless mode ( i.e not calling the open(container) function) I get:

kubebox.js:2633 TypeError: Cannot read property 'width' of undefined at Terminal.resize (xterm.js:4099)

Which corresponds to this line.

Which is expected since open() wasn't called and so this.charMeasure is undefined. I'm not sure this is needed when running headless. I removed the line and it seems to be working.

If it is needed we could mock the DOM elements by using something like JSDOM?

Thanks!

Yes it shouldn't be needed as it's measured when open is called.
