`brave.com##li:has(> span:has-text(Why Brave))`
This works in uBlock Origin, it hides the `
Are these kinds of nested procedural filters supposed to be supported?

Research direction
Start by reproducing the reported behavior with the nested filter `brave.com##li:has(> span:has-text(Why Brave))` in the adblock engine. Trace how procedural filters are parsed and evaluated, then verify whether nested filters are intended to work and define completion as matching the expected uBlock Origin behavior or documenting the supported limitation.
