Truncated text3D when combined with persp3D

I'd like to use text3D with persp3D to rename and format rotated axes' titles, but that of y0 is truncated.
Does anyone know why?
Thanks for help

library(plot3D)
par(mfrow=c(1,1), mar=c(2.5,0,0,4))
persp3D(x = x0, y = y0, z = z0, border="black", resfac=0.5,
        lwd=0.3, zlim=c(11.3,12.5), theta=-65, phi=15, bty = "g", expand = 0.8,
        ticktype="detailed", xlab=NA, ylab=NA, zlab=NA, axes=TRUE,
        colkey = FALSE)
text3D(55, 320, 11.2, "x0 is ok", adj = 0.9, add = T, srt=72, cex=1.5)
text3D(5.2, 359, 10.98, "y0 is truncated", adj = 0.9, add = T, srt=345, cex=1.5)
text3D(0, 405, 11.95, "z0 is ok", adj = 0.8, add = T, srt=95, cex=1.5)

As Darren said here, "text3D() allows expressions to display mathematical annotation. Remember to set the graphical parameter xpd to TRUE, or the text will be clipped when out of the "plot" region."

So, adding xpd=TRUE within par() works perfectly:

par(mfrow=c(1,1), mar=c(2.5,0,0,4), xpd=TRUE)
persp3D(x = x0, y = y0, z = z0, border="black", resfac=0.5,
        lwd=0.3, zlim=c(11.3,12.5), theta=-65, phi=15, bty = "g", expand = 0.8,
        ticktype="detailed", xlab=NA, ylab=NA, zlab=NA, axes=TRUE,
        colkey = FALSE)
text3D(55, 320, 11.2, "x0 is ok", adj = 0.9, add = T, srt=72, cex=1.5)
text3D(5.2, 359, 10.98, "y0 is truncated", adj = 0.9, add = T, srt=345, cex=1.5)
text3D(0, 405, 11.95, "z0 is ok", adj = 0.8, add = T, srt=95, cex=1.5)
