WebViewer Javascript errors on macOS Sierra

I'm initializing a Web Viewer with a data URL, to display a Summernote text editor. This is working perfectly on my local FileMaker 17.0.7.700, running on macOS Mojave 10.14.6.

When I try the same on a remote machine running FileMaker 17.0.7.700, and macOS Sierra 10.12.6, Summernote fails to initialize. The debugger for the Web Viewer shows the following error:

SyntaxError: Cannot declare a let variable twice: 't'.
(anonymous function) — summernote.min.js:2

When I copy the data URL and paste it into Safari on the same remote machine, it loads fine.

The solution is hosted on FileMaker Server 16. I'm referencing the needed JS & CSS files from a CDN (Summernote, jQuery, Bootstrap) in the <head>.

Any ideas what is causing this JS error? I'm waiting to hear back, but I think a client is experiencing the same issue on macOS High Sierra. 🤦‍♂️

Actually it works A-OK on macOS High Sierra, and FileMaker 16. So the issue seems to be constrained to macOS Sierra, and is no longer a high priority issue for me.
