Using TabbedTextOut function to output text, the text will be truncated

In standard C++, I am using 'TabbedTextOut()' function to output text.

My application calls the function more than once with the parameter 'nTabOrigin' set to the same value each time. So that I call 'TabbedTextOut' function several times for a single line.

Such as I output text 'jumpto A', firstly I output 'jumpto' by using ''TabbedTextOut(...)', then I output ' A' by using 'TabbedTextOut(...)'.

But I found that the character 'o' had been truncated. When the font was set 10, the phenomenon was obvious. Is it a bug of this API?
