HTML style attribute inconsistency

[ctjhoa]

Hi,

I found an inconsistent behavior depending on ember versions and ember-angle-bracket-invocation-polyfill.

Here is my ember-angle-bracket-invocation-polyfill version: 2.0.1 (but I reproduce the same issue in 1.3.1)

With classic component declaration:

{{test-me style="color: red" }}

In Ember 2.18.2: the style attribute doesn't exist in the final DOM.
In Ember 3.4.4: the style attribute doesn't exist in the final DOM.

If I try this:

<TestMe style="color: red" />

In Ember 2.18.2: the style attribute doesn't exist in the final DOM.
In Ember 3.4.4: the style attribute exist in the final DOM.

IMO the expected behavior is that style attribute should be transferred to the final HTML node as style isn't prefixed with @.

If I try with another attribute than style (like data-foobar="foobar") it is transferred to the final HTML node as expected regarding the Ember versions

After further investigation it appears on Ember versions < 3.1

I've created a PR which add my test case (feel free to close it).
Here are ember try:each results:

Just wanted to point out that the two invocations are actually different:

If your classic component (curly) invocation was:

{{test-me style="color: red" }}

Then your angle bracket invocation should be:

<TestMe @style="color: red" />

But in your original description you mentioned that you used <TestMe style="color: red" />.

@rwjblue yes it was just to give an output comparison but invocations are different. Do you have any hint where to start to look at to contribute to the polyfill?
