Description

Check before setting initial border image styles Border-image and its friend mask-box-image are shorthands that expand out into 4 css properties[1]. When setting the initial values for these we would blindly create a new NinePieceBorderImage which is large and contains non-trivial destructors. This patch first checks whether the current value is already equal to the initial value before setting.
