I can improve the condition which checks whether the value is a number,
which would solve the case I have stumbled upon, but infinitely many
other cases would remain.

The root cause is that we do not distinguish between textual and numeric
properties, so whenever we get a style property, which looks like a number,
we parse it as a number and then convert it back to a string if needed.

Unfortunately, the conversion from a string to a number and back is lossy:
for example, all the strings "0", "00", "0.0", "-0", and "+0" are interpreted
as "0".

This is obviously not right and I am willing to fix it, but I admit I do not
see a simple solution. Could you please give me a hint?

By the way, what is the reason for translating empty names to the string
"undefined"?

				Have a nice fortnight
