…right (#1375)

Part of #1258

## Proposed Changes

- migrate tests to playwright

<!--
## Things to check

- [ ] Does the change need to be documented?
- [ ] Does any existing example code needs to be updated?
- [ ] Is the change properly tested?
- [ ] Is it helpful to provide another example to demonstrate the new
feature?
- [ ] Are there other code lines that need to be modified?
