Profiler documented code broken rendering

[Atcold]

Version

3.1.9a

Details

In the Profiler Library, we can see:

There's a missing { before the 1, at the end of the line. I checked the source code, and the { is actually there.

https://github.com/pgf-tikz/pgf/blob/89a9ef189a7420e0510fe97907285804bee4f670/doc/generic/pgf/pgfmanual-en-library-profiler.tex#L34-L36

So, I don't know how to fix this bug.

Note to myself: \pgfkeys is parsed specially, but for some reason that special parser jumps over the } and swallows the { after that.

Currently the code does not handle the case where a closing brace is encountered before the first opening brace, so it just keeps on scanning. This might fix it.
