Ah yes very sad that functionality to set widths and heights in facet_grid is gone.

Another possible workaround without ggplotGrob is to set the text angle in theme(strip.text.x=element_text(angle...)) and facet text wrapping in facet_grid(... labeller=label_wrap_gen(width...)), e.g.

ggplot(df, aes(x,y,color=i)) +
  geom_point() +
  facet_grid(labely~labelx, scales='free_x', space='free_x', labeller=label_wrap_gen(width = 10, multi_line = TRUE)) +
  theme(strip.text.x=element_text(angle=90, hjust=0.5, vjust=0.5))
