Sketchup Web fails to load on Webkit-based browser on GNOME/Linux

I am having trouble loading the web app on a webkit-based browser, which identifies itself as “Mozilla/5.0 (X11; Ubuntu; Linux x86_64) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0 Safari/605.1.15 Epiphany/605.1.15 (Web App)”

A Javascript Error is thrown:

Unhandled Promise Rejection: TypeError: ‘arguments’, ‘callee’, and ‘caller’ cannot be accessed in this context. in https://app.sketchup.com/prod/2020-01-29--17-47-06--784de95/static/webapp.js.jgz

Since I assume this is a unsupported browser this will not get much attentions, but perhaps someone has an idea, or there is something fixable on the webapp developers side.

did you try Opera…
