The jtreg IntelliJ plugin can create run configurations for jtreg tests in a variety of ways. One way which currently doesn't work that well is creating run configurations by using the context menu.

For example: when a user right-clicks in the middle of a test method, the JTReg run configuration producer does not recognize that we are trying to create a run configuration for that test method, and instead falls back to creating a run configuration for the whole file.

We can fix this by looking up the first enclosing parent of the line that we can create a configuration for.
