Detailed Problem Description

Firestore allows to have a map field, whose keys contains slashes, e.g. abc/def/123. You can write a document from js sdk with that kind of fields and keys, however if updating doc with nested field dot notation it throws error: Paths must not contain '~', '*', '/', '[', or ']'. The docs says: A quoted field name starts and ends with the backtick character. For example, foo.`x&y` refers to the x&y field nested under the foo field.

I know that FieldPath can be used and it works with FieldPaths, but it should work also with backticks.

Steps and code to reproduce issue

updateDoc(doc(getFirestore(), "doc123"), {["abc.`def/123/455`"]: true})

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
