[FIX] website: hide the "animation launch" option for imgs in dropdowns

Since [1], that feature was lost because a `_computeWidgetVisibility`
was duplicated inside of the same class. The feature is now restored,
indeed the option does not make sense as animations will always launch
on every dropdown openings no matter the configuration.
