The color input tab with the opacity slider.

If you slide the opacity slider of a color input a crash occurs. Initially safari tries reloading the page but then if you try again though safari crashes the tab with the message "A problem repeatedly occurred  with "{url}". 


If you go to the MDN doc site and mess with the color inputs in the example you can trigger the crash: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/color. Or you drop `<input type="color" value="#e66465" />` into an html file and open it and mess with that.
