Description

When a Border.StrokeDashArray is initially set to a dash pattern (e.g., { 4, 2 }) and then later updated to null, the dash pattern remains visually applied. The property change does not reflect in the UI as expected.

Expected Behavior

• Setting StrokeDashArray = null on a Border should remove the dash pattern and render the border with a solid stroke.

Actual Behavior

• Once a dash pattern is applied to StrokeDashArray, setting it to null does not clear the pattern.
• The previous StrokeDashArray values are still visually applied.
