Setting dark mode just after the window open via scripting doesn't work on auto dark mode

[1024]

Because time line of this case is:

1. window open (via script)
2. turn dark mode off (via script)
3. finish image loading
4. turn dark mode off if the image is white

Wait svgView load at the fist time async (resolve #42, #43)
