Irritating behaviour with line style and "close line and fill with colour"

[Graf Geo]

I haven't used this function before and have now played around with it for the first time. "Close line and fill with colour" can be very practical for certain routes.

The function cannot normally be used together with patterns and/or colouring modes (except plain colour) (why not?). If I select arrows as patterns or altitude as mode, "close line..." is deactivated and vice versa.

Strangely enough, both are suddenly possible if I manually restrict the altitude mode to a certain range.

The altitude range of the example route is 41 - 96 metres. If I limit it to 80 - 96 m in coloring mode altitude, the colouring mode is suddenly displayed and the line is filled. However, this only applies to the areas between the route sections outside the set range. The line filling is therefore only applied to the part of the route for which no colouring mode is displayed. This is confusing to say the least. See screenshots.

Thanks for this bug report.

To speed up rendering, tracks are split into multiple lines in case, any coloring or symbols are used => impossible to fill now easily, because whole line is not a single line in the code.

If this may be a major limitation to anyone, there is a solution that will cause a performance reduction, but for now, I'll correctly disable this functionality.
