How to control z-order of glyphs in Bokeh?

Question

I was browsing through examples, docs, and Google, and I cannot find an example or explanation of how to do this simply ...

I use the JavaScript library directly, and when I add a glyph to the graphic, I just want to specify the display order of this glyph. I have glyphs that intentionally overlap, and I need to indicate that one of them is on top. I believe I can get a list of all the renderings using figure.renderersand sort them manually, but this seems like an incredible comedy and rude ...

I tried using a parameter levellike

figure.text(x, y, 'text', {
  text_align: "center",
  text_baseline: "middle",
  text_font_size: {
    value: '8pt'
  },
  level: 'overlay'
});

but i always get the error

bokeh-0.12.0.min.js:3 Uncaught Error: Text.set('level'): level wasn't declared
