Tooltip for channel-names in FX-mixer inconsistent

LMMS 1.1.90-RC2.8

Issue description:
Displaying FX-channel-names with tool-tip is unpredictable inconsistent
Example :
In both examples, the mouse is over the red dot.

Here the tool-tip only shows FX1 and not the channel-name

Here the channel-name of the next channel is shown in the tool-tip

I have tried with both new and old projects, and some are fine, some has it messed up
I have no explanation for the behaviour
So far i know:

• It is not connected to the version of creation
• it has not to do with focus
• not related to muted

I've also noticed some possible odd behaviour there but as you've noticed too it's intermittent. Just acts up when it feels like.

Oh, good, I don't have to make any screenshots for this issue. :)

I also noticed the same issue and eventually noticed at least one reliable cause:

• Track Gear Wheel (e.g. on Triple Oscillator track) > FX 0: Master > Assign to new FX Channel.

This will result in a FX Channel tool tip with "FX 1" rather than "TripleOscillator" as expected.

"Double-clicking on the FX Channel name" and ("hitting enter" or "clicking off the name") will result in the tool tip displaying the correct result. (Which I sometimes do accidentally so hadn't noticed the connection previously.)

I've yet to look into the code to see why this happens as I'm also looking into a bunch of other issues but hopefully being able to reproduce the issue is a start.

I've also noticed (maybe only once?) the actual channel name and tool-tip being the truncated form with an ellipsis ("...") but it may be unrelated.
