Get tests running on firefox browser

[prushforth]

Ensure all tests can run and pass on firefox browser:

• [x] reticle.test.js
• [x] axisInferring.test.js
• [x] queryLink.test.js
• [x] featureLinks.test.js
• [ ] layerContextMenu.test.js
• [ ] viewerContextMenu.test.js - the cause of this is apparently a bug in playwright/firefox.
• [ ] mapContextMenu.test.js - - the cause of this is apparently a bug in playwright/firefox.
