Previously, new `Recorder` instance was given an existing
`InjectedScript`. However, we built a separate source for
`InjectedScript` vs `Recorder`, and both bundles contain their own copy
of all helper modules, e.g. `roleUtils`.
This resulted in two copies of helper modules, which is troublesome for
any module-level globals like a top-level cache. Depending on whether
`Recorder` or `InjectedScript` called into the helper, they would access
the different value of a module global, which lead to bugs.
To prevent this, we force any external dependencies to be imported
through the `InjectedScript.utils`.
- prefer `role=checkbox` over `input[type=checkbox]`
- prefer `#id` over `input[type=checkbox]` and `role=checkbox`
- prefer `text=foo` over `internal:has-text=foo`
- ignore `none` and `presentation` roles
- remove non-strict support
- Rename internal selectors `has`, `control` and `attr` to
`internal:has`, `internal:control` and `internal:attr`.
- Fix `getByLabel()` to respect strictness, by introducing
`internal:label` selector.
- Move tests essential for ports to `selectors-by.spec`.
