Issue created by <https://github.com/mole99|mole99>
This commit added `Metal1.filler` under the `Passiv.drawing` of the sealring: <https://github.com/IHP-GmbH/IHP-Open-PDK/commit/516b01c3a0f7a7a1d6e0dfe2875fceddd97c84e7|516b01c>

This is a violation of rule `M1Fil.a2`, as its side is much larger than 5um.

<https://github.com/sergeiandreyev|@sergeiandreyev> Do you remember why this change was made? Perhaps to fix the density violations of a specific design?
