The "secondary" touchpoint reverts to the previous position when the "primary" touchpoint is released and re-engaged on WebGL applications

How to reproduce:
1. Open the “webgl Multitouch test.zip“ project
2. Open the “SampleScene”
3. Build the project for WebGL
4. In the Player enable the Debug mode (with the UI Toggle)
5. Press and hold a finger on the “red“ side
6. Press and hold another finger on the “green“ side
7. Let go of the first finger (“red” side)
8. While holding, drag the second finger some distance (“green“ side)
9. Press and hold a finger on the “red“ side again
10. Observe the Debug text of the Player

Expected results: The “secondary” touchpoint position (“green“ side) is independent of the “primary” (“red“ side) touchpoint
Actual results: The “secondary“ touchpoint position translates back to where it was (until it is updated) before the “primary“ touchpoint was released

Notes:

• On multi-touch testing websites there does not seem to be the “primary“ touchpoint dependence like there seems to be on Unity WebGL builds
• When successfully reproduced, the corresponding Debug line usually features a relatively large number (“… drag = <~100-2000>”), and on the very next line, the same negative number (to indicate, that the “secondary“ touch-point changed to the first position, and then went back to the current position)
