Using Segmentation Tool in combinations

[liuy129]

Describe the bug with polygon-type tool is activated, our user firstly places a starting point at some region of interest, then he/she tried to zoom in an image or even pan to move the view of the image. after that, he/she finishes labelling the other region and picks the starting point of polygon to finish off the label. However, This panning or zooming in/out will cause the polygon label fails to be generated as label.

This combination of labelling steps works fine with the brush-type or rectangle-type shape tool.

To Reproduce Steps to reproduce the behavior:

1. Go to any label studio task and start labelling
2. Click on 'polygon' to place a starting point
3. zoom in the image and pan to the other side of region of interest
4. continue to finish off labelling by de-select pan option
5. choose starting point of the polygon to finish off the label
6. the new label just created will not show up on the list of annotated object on Label Studio

Expected behavior user should be able to pan or zoom in while they are labelling the same object with polygon-type tool.

Environment (please complete the following information):

• OS: Windows 10
• Label Studio Version 1.7.2 dev
