when I press Clear log it will clear the contents of textarea in UI, but it seems it still remembers its contents in backend. When I start project again it will load the old contents from the backend, and appends new logs after it.
What is probably missing: - clear log also on backend when user presses Clear log action
- if "Clear log on start" checkbox is checked, send it with all other settings to backend so that project knows it should clear its log before it starts.
