Setting the no-render flag on an elm widget had no effect,
as it was not properly propagated to its children. This should
fix that, but I'm not a fan of the solution.
Fixes T3371

so there was/is a case where when an elm window is resized from
outside, it will happen to use the last known size (maybe old) and end
up requesting a resize to that size again itself. it basically
triggers its own resize request as a result of resize events. this
fixes that and stops the loop
@fix
this resolves the issue of all elm windows being created at 1x1 and
immediately resizing to another size after being shown, causing all
kinds of failures in various environments
