This is filed per bug 1168891 comment 16. After bug 1168891 is landed, Fennec will support swappable carets, which matches the convention of Android platform. And the swappable carets will become the default if user turn on "layout.accessiblecaret.enabled" on all the desktop platforms. In the latest B2G text selection spec bug 921965, page 12, it explicitly says that the carets can't cross each other. Given the new capability of the swappable carets, is B2G still prefer the non-swappable caret? If yes, we can resolve this bug as won't fix. Otherwise we can make carets swappable on B2G as well.

NI for comment 0. This is a UX decision.

I agree that swappable carets will provide better user experience. I've updated the spec(p12. dragging leftward & dragging upward part). Please check the attachment.

Tori, thank you for updating the spec. I'll update the code for B2G accordingly.

According to the latest Firefox OS text selection spec 1.7, the carets are now swappable. Review commit: https://reviewboard.mozilla.org/r/46025/diff/#index_header See other reviews: https://reviewboard.mozilla.org/r/46025/
