From the SVG spec The value of the ‘viewBox’ attribute is a list of four numbers <min-x>, <min-y>, <width> and <height>, separated by whitespace and/or a comma... Currently try_parse_view_box will fail to parse the attribute if the values are separated by commas. This change replaces try_parse_view_box with a more correct implementation. It will reside in the AttributeParser.cpp. This new implementation correctly handles comma-separated viewBox values, and is also more robust against invalid inputs. Additionally, it adds a new test case to ensure viewBox values with various syntax are parsed correctly and invalid values are rejected.
