Compass icon cannot show properly in Google Street View widget of ArcGIS JavaScript 3 application

[SailiTang_HW]

Hi,

I am developing a Google Street View widget for our ArcGIS JavaScript 3 web application. Everything is working well except the Compass icon cannot show properly. Please see my compass in the red circle of the screenshot below. it should be like

but the compass icon is shown as follows:

I opened it using Edge but also tried it on Firefox and showed the same issue. Do you have any idea about the compass icon issue? Is ArcGIS JavaScript 3 not compatible with Google API? Or there is another reason?

Thanks for the help!
