[NTG-context] Expected behaviour of \definelayout

[louis.ad@hotmail.ch]

Hello,

I am new to ConTeXt and was trying to understand whether the following behaviour of \definelayout is expected.
Consider this example,

> \setuplayout[grid=yes]
> \showgrid
> \definelayout[odd][
> 	backspace=50mm,
> 	width=90mm,
> 	topspace=20mm,
> 	header=0mm,
> 	footer=0mm,
> 	height=250mm,
> ]
> 
> \starttext
> \showframe
> \dorecurse{10}{\input knuth }
> \stoptext

which I compile with `context example.tex` (ConTeXt Process Management 1.06, current version: 2024.02.27 09:18, obtained via TeXLive 2024).

While the document's layout updates on page 2 (at least, what's being shown by \showframe), the text is typeset using the previous (page 1) layout until it encounters the next \par.
This repeats on the transition from page 2 to 3.
I have tried to look for an answer in the following texts to no avail,

- The layout guide: "It's in the details"
- The "ConTEXt Mark IV: an excursion"
- The mailing list: Peter Hopcroft chimed in with a similar issue in Dec 2022 (which I did not manage to replicate; it appears the solution was to enforce paragraphs at the layout change?)

Is this just the expected behaviour of the layout engine or am I missing something in my preamble?
I would very much appreciate your insights, thank you in advance!

Louis
