When a multiline message is added to a progress bar, the progress bar measures the length of all lines combined in a single string without considering whether that string contains new line characters. It is not accurately measuring the number of lines that are displayed on the terminal.
On the terminal, the actual number of new lines is dictated by a combination of new line characters and text extending beyond the terminal width. Due to this bug, the progress bar sometimes clears too many lines when the progress bar is advanced.
The progress bar should instead consider the overlap of $this->formatLineCount and the actual number of lines in the message and then add any remainder.
