[Bug] Scroll position when freezing/unfreezing fields in TreeGrid

[jumple]

Tested with SmartClient_v100p_2015-01-04_LGPL

This can be easily replicated here http://www-demos.smartclient.com/iso...tml#freezeTree

Please fallow these instructions to replicate:

1. Scroll all the way to the right and freeze Gender field - body's scroll position stays unchanged (as expected) but headers scroll to Email field (first unfrozen field).

2. Click on the right scroll arrow - header and body are now in sync.

3. Unfreeze Gender field - scroll position is almost maintained as expected (it changes by a little bit - my guess by the width of Gender field which is fine but would be better if it didn't change at all)

4. Scroll all the way to the right and unfreeze Name field - the scroll position is not maintained at all and grid scrolls to Name field unlike in point 3 above

4. Scroll to the right and freeze Salary - scroll position is not maintained again and grid scrolls to Name field (first unfrozen field)

5. Scroll to the right and freeze Status - same behavior as in point 1 is observed - body's scroll position is maintained but header scrolls to first unfrozen field

The expected behavior would be to see scroll position unchanged when freezing/unfreezing fields.


Thanks
