patch 9.0.2103: recursive callback may cause issues on some archs
Problem: recursive callback may cause issues on some archs
Solution: Decrease the limit drastically to 20
Recursive callback limit causes problems on some architectures
Since commit 47510f3d6598a1218958c03ed11337a43b73f48d we have a test
that causes a recursive popup callback function to be executed. However
it seems the current limit of 'maxfuncdepth' option value is still too
recursive for some 32bit architectures (e.g. 32bit ARM).
So instead of allowing a default limit of 100 (default value for
'maxfuncdepth'), let's reduce this limit to 20. I don't think there is a
use case where one would need such a high recursive callback limit and a
limit of 20 seems reasonable (although it is currently hard-coded).
