Description

Version Used: 17.2-p1

Starting text:

var x =
"""
normal line
	line starts with tab char
""";

image

Select this statement and indent it. The IDE leaves the tab char at the start of the line and inserts spaces after it:

    var x =
    """
    normal line
	    line starts with tab char
    """;

image

This is no longer valid syntax.
