User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Sabayon Chrome/18.0.1025.45 Safari/535.19 Steps to reproduce: Scaled the document using CSS (we're loading an iFrame with an iPad targeted page. iPad resolution is much too big for most desktops in portrait) -moz-transform: scale(0.25, 0.25) Click a select element Actual results: Dropdown was rendered as if the page was not scaled, so it was way out of position and different scale than anything else. Expected results: Chrome & Safari seem to get it right. If the page is transformed, the select element sizes and positions match the scaling of the parent dom elements.
