Highlighting between Code<-> AST doesn't work with Recast as parser

When Recast is selected, clicking in the code (on the left-hand side) or mousing over the AST (on the right-hand side) does not highlight the corresponding part of the AST/code, respectively.
I've used astexplorer in the past and I thought that this used to work.
Switching to another parser, for example esprima, brings back the Code<->AST highlighting, as expected.
