Ik ignores limit rotation constraint

Anyone advise on what I’m missing here?

The upper leg bone here has a rotation constraint, limiting its rotation around the x axis to +/- 45 degrees. Any attempt to manually rotate it beyond those limits is ignored.

However, if I move the foot bone via an ik bone constraint, the rotation constraint on the upper leg is ignored, allowing it to assume what should be illegal positions.

For me., it is too long ago. But maybe change the order of the modifiers?
And maybe, you need a special IK Limit rotation?

To be honest, I don’t used them, these constrains. Too much work, less helpful in my humble projects.
