The attached test case overlays a partially transparent XUL label over <browser> content. If the content contains text input the caret shows above(?) the XUL label instead of being rendered at the layer the inputted text will be rendered.

Reproducible: Always

Steps to Reproduce:
1. Open the attached test case
2. Scroll the google's text input box to be under the red floating label
3. Type some text

Actual Results:  
Blinking caret has different color from text that is seen through the red label.

Expected Results:  
Both the caret and text should look like being in the same color (black on white) but seen through the red label.


If the label is modified to have opacity:1 then only the caret is visible. This might be a duplicate of bug 58359. However, I'm reporting this issue as a new bug because it might get fixed without this getting fixed

Perhaps the caret rendering should be modified so that caret were rendered at the actual content layer. Then any blending effects or like that would affect the actual content would also affect the rendering of the caret. Hopefully that would also fix the bug 28068.

Attachment: Modified testcase from bug 204278

This test case has been modified from the one in bug 204278 by changing the label partially transparent and changing the web page to point to google.com so it's easier to get the input under the label. This test case depends on bug 204278 (which was fixed by bug 317375).
