Edge label is not displayed at the same location when changing the diagram zoom level

[lfasani]

With a manhattan edge if the label anchor is exactly at a bendpoint (for example the border of a vertical edge segment next to a horizontal), when changing the zoom, the point calculation may change and then the edge label is displayed in the bad coordinate system.
We need GMF-Runtime changes to have better point precision.

change in GMF-runtime eclipse-gmf-runtime/gmf-runtime@b4316c6

We should have a reproducible use case in Sirius(currently, we have only a Capella scenario)

Fixed in GMF Runtime 1.16.1, and Sirius Desktop 7.2.1 depends on that.

Here's a reproduction/validation case: test-bug-edge-label.zip

I reopen this issue, it doesn't work.

Step to reproduce:

• Import test-bug-edge-label.zip
• Open the diagram new DTestBugLabelEdge
• Zoom to 100%
• Zoom to 75% or 125%
• KO: the label has moved (Compared to 100% zoom)
