SUMMARY
So i have been editing a video in kdenlive but when i accidently trigger an action such as Set Zone Out, the Chroma Key gets broken and does not show the effect on the Project Monitor but instead removes the image at full effect

STEPS TO REPRODUCE
1. Drag a few clips into the timeline
2. trigger the Set Zone Out action
3. Add a chroma key to a clip
4. Look at the Project Monitor while moving the slider for the chroma key variation

OBSERVED RESULT
The selected color does not get erased out

EXPECTED RESULT
The color should be erased out when an action like Set Zone Out gets triggered

SOFTWARE/OS VERSIONS
Windows: 10
MacOS: Does not have
Linux/KDE Plasma: Does not have
(available in About System)
KDE Plasma Version: N/A
KDE Frameworks Version: N/A
Qt Version: N/A

ADDITIONAL INFORMATION
Can this please be fixed in version 18.12.2 please, its crucial to me.

I have done the following steps in Kdenlive Windows 18.12.1: 
- Drag a clip onto the timeline. 
- Drag the effect Chroma Key on that clip. 
- Select with the drop a color by draw up a square. 
- Clip gets a proper alpha. 
- On the timeline Set Zone Out somewhere within the clip then only the bar on top of the timeline gets shorter/longer. 
- The clip remains the same with the effect on it with the alpha still visible. 

What I’m doing different to you?
