Handler.Feature may not trigger "click" when touching a feature

[erilem]

The feature handler should trigger the "click" callback on each touchstart on a feature. With the current code only the first touchstart triggers a "click" callback.

Expected:

touchstart on feature -> "click"
touchstart on same feature -> "click"
etc.

Current behavior:

touchstart on feature -> "click"
touchstart on same feature -> NOTHING
touchstart on same feature -> NOTHING
etc.
