'&&' in script fragments incorrectly marked as an error

[z0u]

I'm using AngularJS (1.4), which requires that I have JavaScript-like expressions in HTML attributes. The problem is that & and && in expressions such as ng-if="!edit.model && !model.length" are marked as an error and highlighted red:

I think this syntax should be considered valid HTML, because it's not an ambiguous ampersand.
