<pre>I did a bit of digging into this. Since the change in question, if the platform's RenderTheme does not support meter, HTMLMeterElement::createElementRenderer() will not create a RenderMeter. WebCore Accessibility for meters currently assumes we have a RenderMeter. So either we need to make change in how WebCore Accessibility does its thing, or RenderThemeGtk needs to start supporting meter.
Because I am completely RenderTheme ignorant, I don't know how easy doing the latter would be. But a quick test (having createElementRenderer() return a RenderMeter despite the fact that RenderThemeGtk doesn't support it) caused meters to become accessible again via ATK/AT-SPI2.</pre>
