 The `utils.curveIntersectsX()` function finds the point(s) where a curve
 intersects a given X-value.
 
+<Warning>
+This function can sometimes fail to find intersections in some curves
+due to a limitation in an underlying Bézier library.
+Please see [Bug #3367](https://github.com/freesewing/freesewing/issues/3367)

 Instead of a path, you describe a single curve by passing the four
 points that describes it.
