1. Goto https://element-capture-demo.glitch.me/
2. Open devtools and type devicePixelRatio to observe the value is e.g. 1
3. Capture and restrict to Element
4. Type devicePixelRatio again and observe it has doubled, e.g. 2

The changing of devicePixelRatio is messing up my canvases...

I am not sure if this is an element-capture issue or a general screen capture issue, and I did not find answers in the specs.

Is this intended behavior? If so why? and how could I deal with it? I also tried to play with resizeMode and logicalSurface properties to prevent this, but they had no effect.
