In xsltforms-493 and earlier, xforms-ready is dispatched immediately
after xforms-model-construct-done, but before the UI is ready.
The UI should be ready before xforms-ready is dispatched.
For example, if you want to display a page, and load additional
resources on xforms-ready to display when they return, you would perform
the final submissions on xforms-ready.
In the current implementation there is no difference between doing this
on xforms-model-construct-done and xforms-ready because both block the
initial page display.
I have not examined all aspects of this problem, but I noticed the
following simple change will fix it:

Here is a test case. Without this change, or a similar one, the whole
page blocks and then you see A and B at the same time.
With it, you see A, then a pause, then B is added.
