[Glimmer 2] textarea renders "true" instead of ""

[GavinJoyce]

The rendered value of textarea is "true" instead of "" when the context value is "".

TODO:

• Create a failing test @GavinJoyce: fix <textarea> empty string values glimmerjs/glimmer-vm#250
• Fix: fix <textarea> empty string values glimmerjs/glimmer-vm#250

Given the following controller:

export default Ember.Controller.extend({
  textareaContent1: '',
  textareaContent2: 'some default text',
});

And template:

textareaContent1: {{textarea value=textareaContent1}} <br />
textareaContent2: {{textarea value=textareaContent2}} <br />

htmlbars renders:

glimmer renders:

This doesn't happen for {{input}}.

We're calling normalizePropertyValue for value on textarea which converts a "" value to true:

https://github.com/tildeio/glimmer/blob/9ecc9ade7efa41cf7068729ddeea4b09c1ce51de/packages/glimmer-runtime/lib/dom/props.ts#L33-L39

Should this use normaliseTextValue like INPUT?

Reopening here until we bump glimmer versions.

This is the only bit preventing EPS from work in glimmer2. I've even reduced the reproduction even more: https://ember-twiddle.com/64618480b3b1507f8d73475007f9b2a0?openFiles=templates.application.hbs%2C
