should not have distance measurement labels on interactive pv image

[kswang1029]

Describe the bug
reported by @jott3077

When there is an interactive pv preview widget, if we enable distance measurement on the main image (left image in the screenshot), we will see "0.000000" label rendered on the interactive pv image (right image in the screenshot). On the static pv image generated via the pv generator, it works fine (middle image in the screenshot).

To Reproduce
Steps to reproduce the behavior:

1. load an image cube and enable interactive pv preview
2. enable distance measurement tool in the main image viewer
3. make a measurement
4. we will see "0.000000" label appears on the interactive pv image.

Expected behavior
no distance measurement labels on the interactive pv image
