Ordering of features with z-index not working

[rurseekatze]

Ordering features with z-index to determine their rendering order does not work correctly in some cases.

I guess that the problem occurs when using splitted MapCSS rules where multiple rules match on one feature (like in the example). It is also thinkable that z-indexes dynamically created with eval() are not supported by parts of the code. Therefore analyse what is happening here:

node-tileserver/kothic/style/style.js

Line 79 in 034152a

styleFeatures: function (features, zoom, styleNames) {

Example:
Speed signals and the used MapCSS stylesheet.
