Test explorer doesn't show suite correctly

Expected Behavior

Javascript tests are displayed in VS Test Explorer by Project > File > Suite > Test

Actual Behavior

The tests output shows the details of file::suite::test

Creating Test Case:tests\FormatServiceTests.js::FormatService - format()::date
Creating Test Case:tests\XAxisTests.js::global::XAxisService.axis() - Index Values

But the test explorer seems to split on the last . and shows js instead of FormatService - format()
and XAxisService > axis() - Index Values instead of global > XAxisService.axis() - Index Values

These examples are in Jest (26.4.2), but I've seen the same issue trying Jasmine.

FormatServiceTests is using

describe("FormatService - format()", () => {
    test("date", () => {
        ...
    });
});

while
XAxisTests is a top level test

test("XAxisService.axis() - Index Values", () => {
    ...
});

• Visual Studio Version: 16.8.0 Preview 3.2
• Node.js Version: 10.15.0

Steps to reproduce

1. Create a .netstandard project following https://docs.microsoft.com/en-us/visualstudio/javascript/unit-testing-javascript-with-visual-studio?view=vs-2019#unit-test-net-core-and-net-standard
2. Add test files into the tests folder and rebuild the project

Reproduce the issue using the provided .NET Standard project steps, with the Jest or Jasmine examples from the report, and inspect how Visual Studio Test Explorer parses file::suite::test names. Done means the explorer preserves the Project > File > Suite > Test hierarchy, including dotted filenames, suite names, and top-level tests.
