Viewer Crash: when using contextOptions

[Nikitak211]

while trying to make Viewer container transparent, using -
contextOptions: {
webgl: {
alpha: true,
},
}.

scene is suddenly undefined after it passes as filled.

using version 1.16.1

thanks for any help.

Found a solution, Suggesting added it to documentation for those who need transparent map

when using contextOptions u need to use "useCesium" in children and not use the ref of viewer, other wise its crashing the viewer.
