wasm: Refractor Selenium manual test into auto test

Using Selenium for WebAssembly testing enables us
to test user interactions, which is very valuable.
Turning this test into automated allows us to run
it in CI pipeline. This will help with detecting
regressions.
Two of these tests are currently failing on CI
machine and they have been temporarily disabled.
