Mixer window loses focus when moving channels

[StakeoutPunch]

LMMS Version: 1.2 RC4, Win64
OS: Win10

Issue:
The mixer window will lose focus when moving channels across channels that contain VST effects.

Steps to Reproduce:

1. Create 3 mixer channels
2. Add a VST plugin to channel 1
3. Move channel 3 over channel 2 using the right click menu or by using the Alt+Arrow Key shortcut
4. Window is still in focus
5. Move channel 3 over channel 1 using either method

The Mixer window is no longer in focus. It will lose focus any time step 5 occurs. This bug is extremely annoying and a time drain when trying to move channels across large mixers in larger projects that contain many VST effect plugins.

1.2RC4 win 32 xp3
Cant reproduce with either alt-method or context-menu
Perhaps win64 only?

edit
Came back to this, and removed Channel-3
That gave a strange result:

There are two things here,. The channels should have been named with the instrument-names, not FX(n), and there should ofcause not be two FX1.
Here is the mmp-project:

Logically i guess its ok, so its really a cosmetic, yet confusing glitch

RC4, Win 10 64bit Reproduced with Ambience and LittleAlterBoy, both of which have a "controls" button on the effect and a GUI. Doesn't occur with mda De-ess or mda Image, neither of which have a "controls" button. Moving an FX channel with an offending VST effect also causes the mixer to lose focus. So it seems like any time a mixer channel containing a VST effect with a GUI changes position, mixer focus is lost.
