caret: Fix toggling behavior with QtWebEngine

The behavior when pressing `v` in line selection mode was different between
QtWebKit and QtWebEngine: With QtWebKit, normal selection mode was entered,
while with QtWebEngine, selection mode was left.

Do the former with QtWebEngine as well, as that's also what vim does.
