Description
I could not remember if id is an allowed reflected attribute binding — so I gave it a try and got an error message that was a bit confusing:
id: {
type: String,
reflect: true,
input: ['data'],
compute: this.#computeId,
},
Results in error message:
Uncaught Error: Property "MyElement.properties.id" is computed (computed properties are read-only).
Is this expected?
