Annotation stay its line or is moved when InsertText with line break is called. It depends on if the current line is empty or not. #498

Hello, I have observed the following behavior. I have a line with annotation and I am inserting a text that starts with one or more line breaks.

  1. If I insert the text on the end of an empty line, the annotation will be moved to the last added line.
  2. If I insert the text on the end of a not empty line, the annotation stays on the current line.
m_rScintilla_TextArea.ClearAll();
m_rScintilla_TextArea.InsertText(0, "abc\r\r\rdef");
SetAnnotationOnEachLine();
DebugAnnotations();
Debug.WriteLine("Inserting line break with in the middle of a text (end of second line) on an empty line. Annotation will be moved into new line");
m_rScintilla_TextArea.InsertText(4, "\rnew test");
DebugAnnotations();
/*
// Generates
Line | Annotations | Text
0|This is an Annotation for Line 0.|abc
1|This is an Annotation for Line 1.|
2|This is an Annotation for Line 2.|
3|This is an Annotation for Line 3.|def
Inserting line break with in the middle of a text (end of the second line) on an empty line. The annotation will be moved into the new line
Line | Annotations | Text
0|This is an Annotation for Line 0.|abc
1||
2|This is an Annotation for Line 1.|new test
3|This is an Annotation for Line 2.|
4|This is an Annotation for Line 3.|def

Debug.WriteLine("\n");
m_rScintilla_TextArea.ClearAll();
m_rScintilla_TextArea.InsertText(0, "abc\rSOMETEXT\r\rdef");
SetAnnotationOnEachLine();
DebugAnnotations();
Debug.WriteLine("Inserting line break with in the middle of a text (end of second line) on a non empty line. Annotation will stay on the line of position of insertion.");
m_rScintilla_TextArea.InsertText(12, "\rnew test");
DebugAnnotations();
/*

3|This is an Annotation for Line 3.|def
Inserting line break with in the middle of a text (end of the second line) on a non-empty line. The annotation will stay on the line of the position of insertion.

DebugAnnotations() and SetAnnotationOnEachLine() not added because of brevity

Are there any rules that I have to obey by inserting text with new lines concerning annotations?

Thanks & seasonal greetings Filip, Bremen
