[BUG] Cubeviz: Tabbed viewer is blank on initial selection

[rosteen]

See the video below for a demonstration. Essentially, if you drag the second image viewer in Cubeviz to be tabbed inside the first viewer, when switching to the other viewer it will show as blank until something like a resize (of the viewer or browser) forces an update, at which point the data will display as expected. The expected behavior is that you can switch between viewer tabs and have the data display normally.

I've made a PR for bqplot for this: bqplot/bqplot#1531

[pllim]

@mariobuikhuizen , just to clarify, this bug needs both PRs that you mentioned?

• fix: display and resize plots when not in a lumino context bqplot/bqplot#1531
• fix: workaround for blank tabbed viewers after selection #1718

[kecnry]

@pllim there is a comment in #1718 that it is just a patch and can be removed when the bqplot fix is released.

[pllim]

For clarification, will #1718 break if we use it in conjunction with bqplot/bqplot#1531 ? That is, are the patches mutually exclusive and hence we need #1718 to pin a bqplot maxversion?

[mariobuikhuizen]

It will not break when the bqplot change is made, it will only cause an extra update event, which will subsequently be debounced.
