Fix empty nav ToC in topic with to-content chunk #2577
Fix empty nav ToC in topic with to-content chunk #2577

When a topic is chunked to-content a #id is added at the end of the file name in the @href.

When creating the `current-topicref variable` :

```
<xsl:variable name="current-topicrefs" input.map//*[contains(@class, ' map/topicref ')][dita-ot:get-path($PATH2PROJ, .) = $current-file]"/>
```
The result of dita-ot:get-path contains the #id therefore the condition is never met.
