I discovered .editorconfig has priority over jedit properties inside the file, like :tabSize=8:
However jedit reads these properties also at buffer save, while EditorConfig does not. EditorConfig behaviour should be consistent and not change after buffer save. Maybe after save the editor config should reload the properties, like it does after load.
tab_width = 3
indent_size = 3
2. inside the file:
After opening the file, tab moves by 3. After save: by 8.
Expected behaviour: don't change the step after save.
