Request getIsLivePreview() not working

[putyourlightson]

The following appears to be returning false even in live preview requests (when it should obviously be returning true), which is tripping up the validation method in the Snaptcha plugin.

Craft::$app->getRequest()->getIsLivePreview()

This is happening as of Craft 3.1, currently seeing it on 3.1.2.2.

After some more investigating, it seems that it is working, but that the check is performed later than it was previously, so that it is not yet registered when the Controller::EVENT_BEFORE_ACTION event is triggered. If this is intentional then I'll update the code on my end.

If the line Craft::$app->getRequest()->setIsLivePreview(true); was moved from:
https://github.com/craftcms/cms/blob/3.1.2.2/src/controllers/LivePreviewController.php#L104
to:
https://github.com/craftcms/cms/blob/3.1.2.2/src/controllers/LivePreviewController.php#L36
then that would perhaps make it more reliable?

Yep, easy enough.

Thanks!
