@alex-powell Thanks for the detailed report and for linking back to your forum thread.
I don't see your quoted browser console error here on latest Chrome and late Firefox. Can you report the browser details you are experiencing this message on? May not be related but good to know just in case.

Linking for context to later improvements made to this area of code that may be relevant:
"regression in dashboard disk activity widget" #1978
and it's associated pr:
"regression in dashboard disk activity widget. Fixes #1978" #1979
With the latter released in stable channel as 3.9.2-42 (1 Nov 2018)

However as the linked issue/pr set pertains to multiple same length by-id names, which are not seen in this issue, and relate to a June 2018 regression, their relevance may be only the include unit tests which should be extended, if need by, in the process of this issues 'fix'. Assuming this issue can be reproduced in the latest stable channel release code.

Closing as pertaining to now defunct base OS. We do have a similar Tumbleweed only issue re no-show disk activity widget with our pending 5.0.9-0 installers but that will be covered in a new issue as it is seen only on TW base, Leap bases of 15.4, 15.5, 15.6 are not currently affected.
