A quick fix for Issue 9762 and 9763.

This is caused by my change r12434 that does not check if there are any other keys pressed when a user presses left-control and left-shift keys (or right-control and right-shift keys).
To fix this issue, this change does not only add the above check, but also it adds code that cancels updating the text direction if a user presses another key while he/she is pressing control and shift keys.

BUG=9762 "Regression: Shift+Ctrl+Arrow selection combination also changes text direction in RTL UIs"
BUG=9763 "Ctrl+Shift text alignment depends of the sides of both the Ctrl and the Shift keys"
