Description M 2019-09-25 14:13:41 UTC

SUMMARY
The stroke preview of the brush editor now stays on the last working brush preview instead of showing the "No Preview for this engine" message for those that don't support it, like the Clone, Quick or Shape engine. This happens in master (git f867486), but not in 4.2.6.

STEPS TO REPRODUCE
1. Open the brush settings
2. Switch between presets that generate a stroke preview and one that doesn't

OBSERVED RESULT
The generated stroke preview of the last working preset stays.

EXPECTED RESULT
The "No Preview for this engine" message should appear, like in 4.2.6.

SOFTWARE/OS VERSIONS
Krita master (git f867486)
