Issue with slides.js and MS Edge

Hello,

Long time user and part of the team at an automotive OEM. We're seeing an issue with Storyline 360 in our SCORM 1.2 player. Normally, these operate correctly, but when allowing user to move backwards and forwards between slides, we get an issue that's not manifesting in Chrome or Firefox, only in MS Edge. When this occurs , the voiceover audio halts and the training needs to exit and restart. It looks like a javascript error where a value isn't passed correctly. Any insight here, thanks? -Al
