Browser crashes after use of MapCSS dashes

[rurseekatze]

Using casing-dashes: 0,0; or dashes: 0,0; in a MapCSS style causes a crash of Chromium (and probably other browsers too).

But why would you need to set dashes to 0,0? Doesn't make much sense...

[rurseekatze]

I know that this does not make much sense, but the program should consider such invalid values to avoid browser crashes. I guess that it would be sufficient to add a check like if (value == 0) break; somewhere in the code.
