Fix Version/s: None
Component/s: display_firefly, Firefly
Sprint:SUIT Sprint 2018-06
Team:Science User Interface
When using the Firefly backend for lsst.afw.display, the first MaskedImage or Exposure displayed via Display.mtv has a wonderful mask overlay (much better than DS9's!).
Unfortunately, if I call mtv a second time on the same Display instance, the mask overlays do not appear, even though the image itself is updated.
If I close the image window in Firefly itself before calling Display.mtv, things work as expected.
If a quick fix is possible, it'd be great to get it in this week so I can avoid demoing the workaround at LSST@Europe3 next week (but it's not a terrible workaround if quick fix is not possible).

It was decided to make a fix on the Firefly server instead of deleting the image before mtv. Unfortunately I am finding the problem is still occurring when using the https://lsp-demo.lsst.codes/firefly.
We were able to reproduce the problem on my laptop. The issue was fixed in review, by this commit. Masks appear reliably now, on my laptop and on the lsp-demo platform.
The behavior of the masks is server-dependent, in my testing. Running the intro-with-globuler notebook and using the lsp-demo.lsst.codes Firefly server, the masks don't appear after the first Display.mtv. On the last-demo.ncsa.illinois.edu server, the masks still display in my testing.
We are testing a fix on the display_firefly side, that would delete the displayed image at the start of mtv.
