As well as not being necessary for the example, it also had the problem of
not actually having the input in focus (there was no press of 'tab' to kick
things off) and so the other keys didn't go into the `Input` as they were
supposed to.
Sometimes, when building the docs, this would end up being a bit of an
"empty" example in that the time taken to get the result back from the API
would be so long that the output would be of the request just in progress.
So we've decided to drop this from the front page.
We copy the mkdocstrings template for attributes so that we can exclude the (default) value for attributes (and class variables) from the documentation as that is generally useless.
As pointed out in #1649, a `ChildrenUpdated` message is documented but it
doesn't exist in the code. It looks like it got added during development,
then removed after it was realised it wasn't needed, but presumably it got
left in the docs:

I've seen a couple or so folk get confused about what a percentage value for
a dimension means, often seeming to think it means that percentage of
the *remaining* space within a container as opposed to a percentage of the
space in the container (note total space, not remaining space).
I'm not sure the wording here is the final form we want (there's more
mention of "dimension" here than your average Star Trek or Doctor Who
episode!), but I think it's narrowing in on it.
Making this change to place-hold the need to improve this and perhaps gather
some input to find the best final wording.
