Data loading into image viewers is slow after update to Jdaviz 3.7

Description

Not a bug per se. Data loading into the image viewers for all viz tools is now noticeably slower after updating to Jdaviz 3.7, with its deps. This happens for images in Imviz, spatial slices in Cubeviz, and spectral image data in Specviz2d. It's noticeable in the MAST web, but also noticeable in a local notebook loading data. The slowdown is after the initial Jdaviz skeleton app loads, when data is being added into the viewers. It now takes ~30-40 seconds to load data into the viewer, whereas it used to take a second or so after the app loaded. The exact packages used in the MAST environment are included in the software versions section.

How to Reproduce

1. Get package from '...'
2. Then run '...'
3. An error occurs.

Expected behavior

Data loading into viewers to be comparable to what it was in Jdaviz 3.4. Or if this is the new normal, perhaps a warning label.
