As long as you don't otherwise need to update your `master` branch, you can wait to reset it until after this PR is integrated. If you prefer to create a new branch and a new PR, then you could link to the discussion. I'll leave it up to you.

I think calling `Runtime::exec("open", uri)` is fine. It matches the behavior on Windows and Linux. I'll do some testing, but I don't anticipate any problems.

In that case, can you create a new manual test as part of this PR? I recommend a new directory: `tests/manual/desktop/HostServices` (my thinking is that `tests/manual/desktop` could eventually include tests for `FileChooser` or other similar manual tests). I'm open to other names as well. You can look at `tests/manual/web/InputTypeAcceptAttributeTest.java` for an example of a good manual test. I recommend adding at least a `.txt` and a `.html` file. You can hard-code the filenames so you don't need to use a `FileChooser`.
