It is not just opening a new tab that can trigger this problem. Even opening and closing another Windows application can trigger it. It is almost as if
anything that takes focus off the page will cause the on-screen keyboard to no longer pop up automatically for that page.

Note that tapping in the address bar (which WILL bring up the on-screen keyboard) seems to "fix" the issue, at least temporarily until something takes focus away from the page again.
