Memory leak on Outlook

[fergy-hs]

Hello,
my company is using analytics.js to keep track of the user's interactions on our Outlook native plugin. The outlook plugin show a modal with an iframe that contains a form. Every time the modal is shown we observe that the memory is normally allocated and every time we close the modal the memory is freed as expected. However if we enable our Segment integration, and start calling analytics.track(), we observe that when the modal is closed the memory does not get deallocated which results in an accrual of memory which ends up crashing Outlook.
Any help with this would be greatly appreciated. Thanks
