[Glimmer 2] failing test for #14001

Failing test for #14001

[rwjblue]

@GavinJoyce - I wonder if we can:

• remove value from attributeBinding here
• add a template for it (in this folder) that has a single {{value}} in it

[GavinJoyce]

@rwjblue spike here : master...GavinJoyce:gj/spike-textarea-template

There are at least two failing tests which I'm looking into now:

[rwjblue]

Based on that failing test, I would say that this method isn't firing when those events are triggered.

@rwjblue I've pushed a "fix" for that failing test, the htmlbars one has three childNodes (two for wrapping the dynamic node I suspect) while glimmer has just one.

I'm not sure how this strategy would work with user input though, especially in htmlbars. I'd like to write some tests that actually send keys to the text area. Do you know of anything like this elsewhere in ember tests?
