fix: add a comment explaining browser type prop

[pauldambra]

follow up to #949

occurred to me to add a comment, but wanted to add that in a PR not from a fork so I can see the testcafe tests pass

this PR will bump minor - despite being only a comment - since #949 can't bump the version as it came from a fork
