15This change is a compatible change. An invalid string that contains digits is not parsed into digits. Instead, it is regarded as an invalid value and is set to the default value according to predefined rules.
16Before change: With the settings of **.arrowSize("100abc")**, the arrow is displayed in a 100 vp size.
17After change: With the settings of **.arrowSize("100abc")**, the arrow is displayed in the default size.
