Get tests running on firefox browser

[prushforth]

Ensure all tests can run and pass on firefox browser:

• reticle.test.js
• axisInferring.test.js
• queryLink.test.js
• 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.
