Defect #8395
closed
Tags start with 'pre' are handled as 'pre' tag in Textile
0%
Description
If you use < and > in your wiki you might have something like:
<previous> <next> etc...
As you can see above the < previous > is handled as < pre > which i think should not be the case and is a bug in the parser.
