I'm afraid that there are no plans to fix this further just now as there are so many more urgent things to do with our time. We would probably not accept user contributions for this either, as it would be likely to add more additional complexity to a tricky part of the code than we could justify.
Current state of support: you can configure whether auto-capture is on or off by default, you can manually toggle it, and at some point we might (but also might not) add some way of easily checking the status in full-screen and seamless mode.
