[panel] indicators jumps left-right when one of them are removed or added

[Lain_13]

When you starting or closing application which have own indicator (like Transmission or Radio Tray) all indicators to the right from place where it added and then all indicators jumps on proper place. It looks really bad.

How to reproduce:
1. Install any application which have own indicator like Transmission, Dropbox, Radio Tray or anything else.
2. Start this application.
3. Close this application.

Actual results:
1. After step two all indicators on panel to the right from newly added indicator will jump to the right (powerbutton indicator will fall to offscreen space). Then after ~1 second all indicators jumps to the left on right place.
2. After step three all indicators on panel to the right from removed indicator jumps to the right (there is gap after poserbutton indicator). Then after ~1 second all indicators jumps to the left on right place.

Expected results:
In both cases only left part of indicators list should jump and powerbutton indicator must stay in place like this set of indicators adjusted to the right side. Small animation with indicators moving to the left or to the right when one added/removed will be fine too.

Thanks for the detailed report Lain!
I cannot reproduce the issue with Transmission on Oneiric. I am guessing the bug has been fixed by yesterday's updates. Could you check again please?

Checked with 3.8.16 ~bzr672 (seems like the latest one) with Radio Tray and Transmission.
I still can reproduce this bug.
I even tested it with and without compositing effects (used 2d-desktop-settings app to disable/enable them).

I can make video if you want but I'm not sure it will be helpful at all.
How could I help to find what's wrong?

video is always useful, you might want to select a specific area on
the screen using gtk-recordmydesktop.

Ok, here it is. I've closed and started again Radio Tray. As you can see all indicators jumps instead of only indicators to the left.
As I told before it would be nice to have smooth animation instead of jumps as well.
