Hello.

Consider the following MWE:

\usemodule[tikz]
\setuplayout[grid=yes]
\starttext
\startstandardmakeup
Not nothing.
\stopstandardmakeup
\stoptext

The output consists of two pages, the first being an unexpected and
undesired blank.
Removal of either tikz, grid or makeup is sufficient to make the blank
disappear.
I am failing to see how these three interact.

My versions:
This is LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238)
ConTeXt  ver: 2015.05.18 12:26 MKIV current  fmt: 2015.10.28  int:
english/english

The bug is reproduced also at live.contextgarden.net too

Here is the related SE question:
http://tex.stackexchange.com/questions/284972/tikz-causes-blank-page-in-front-of-context-makeup-with-grid-layout

Can anyone explain the interaction or provide a workaround?

Thanks.
