AIR 25 StageWebView iOS does not render corrrectly if stage property is null?

This may be fixed in AIR 26, but I've noticed on iOS with AIR 25, that if I load a page into a StageWebView instance before I have set its stage property (or have deliberately set the property to null), the page does not render correctly

The page seems to render with larger font size than specified in the CSS, however the CSS is being partially processed because the font colors are correct.

This problem does not occur on OSX or Windows.

My workaround is to put OS specific code, to render the iOS webviews only when their stage property is set to the main stage

Has anyone else encountered this.

BTW. I have not had chance to test this with AIR 26, as we only released a new version of the App yesterday and its still in user testing, so I can't upgrade to AIR 26 until primary user testing is complete in a few weeks
