host bindings: empty [] / () keys accepted, and aria-* host bindings stay DOM properties #704
Description
Found while reviewing #697. Checked against ngtsc 22.2.4.
1. Empty [] / () host keys are accepted
@Directive({ selector: '[d]', host: { '[]': 'a', '()': 'b()' } })
ngtsc error NG5001: Property name is missing in binding / Event name is missing in binding
Oxc no error; emits ɵɵlistener("", …) and ɵɵdomProperty("", ctx.a)2. Host aria-* bindings stay DOM properties
@Directive({ selector: '[d]', host: { '[aria-label]': 'l' } })
export class D { l = 'a'; @HostBinding('aria-hidden') h = true; }
ngtsc ɵɵattribute("aria-label", ctx.l)("aria-hidden", ctx.h)
Oxc ɵɵdomProperty("aria-label", ctx.l)("aria-hidden", ctx.h)binding_specialization.rs rewrites aria-* to an attribute only for templates (is_aria_attribute), not in specialize_bindings_for_host.
