Either of the
html5.js JS files cause Flot graphs to render blank, since they break Flot's access to the
<canvas> element. These files are loaded when either of the following options (or both) are checked on the theme settings page:
If I turn off those two options (both) for my Zen subtheme, Flot graphs render perfectly in IE8. There was a solution (though probably not ideal) posted to Stack Overflow here: Using Flot with Bootstrap: IE8 compatibility?. It looks like the idea is that you can shiv everything except the canvas element...
Is there any better solution? If not, what would be the recommended way for me to get the shiv, responsiveness, and Flot all working harmoniously in IE 8?
