Effect of #4172 on spinner flicker

[rasmusjagren]

#4172 adds a minimal height to ui elements while displaying spinners to avoid cropping them. This makes sense in most cases, but causes a lot of flicker if the final height of the element is lower than that of the spinner (e.g. if rendering empty cards in a dashboard that will later be filled). It would be good if this feature could be turned off in the setting.

Interesting, thanks for the report. Would you be interested in sharing a reprex and/or screen-recording? Doing so will increase the chances that we'll address the issue

Also, if you want to prevent this behavior, I think you can add this CSS?

[data-shiny-busy-spinners] .recalculating {
  min-height: 0 !important;
}
