TabMixPlus "open last selected on tab close" works incorrect when TGM is enabled

[GoogleCodeExporter]

Before submitting the issue, please check that your version of TabGroups
Manager is the lastest stable one. (Check it in Firefox Extensions).

Tried two last betas
What steps will reproduce the problem?
1. Install TMP (latest stable, dev. build - whatever)
2. Settings in TMP: Events - Tab Closing - When closing current = focus last 
selected
3. Open #1-#2-#3 tabs, then activate #1 -> #2, and close #2 - you'll get #1 
active
4. Install TGMbeta, and in the previous step you'll get #3 active instead. 
Settings from step 2 don't affect the behavior now

What is the expected output? What do you see instead?
see step 3

System Info:
What version of TabGroups Manager are you using?
latest
What Operative System are you using? 32 or 64 bits?
Ubuntu 14.10, x64  
What version of Firefox are you using?

There is a setting in TGM options behind tab "other". I suspect you have select 
select last tab in same group. Please check.
