cyto_plot_gating_scheme() fails on interval gates

[rwbaer]

Describe the bug
I constructed a gating scheme that included two interval gates. cyto_plot_gating_tree() seems to accurately recognize the gatin structure. However, cyto_plot_gating_scheme() seems to fail after showing the 2 gates based on density plots.

To Reproduce
Steps to reproduce the behavior:

# Create gates
# Gate (non-debris) Cells (gating template Samples.csv)
cyto_gate_draw(gsSamp,
               parent = "root",
               alias = "Non-Debris",
               channels = c("FSC-AREA", "SSC-AREA"))

# Gate Single Cells (gating template Samples.csv)
cyto_gate_draw(gsSamp,
               parent = "Non-Debris",
               alias = "Single Cells",
               channels = c("FSC-AREA", "FSC-HEIGHT"))

#=====================================
# Leaf gates (I think is terminology)
# -----------------------------------

# Gate Live Single Cells
# Gate SytoxAAD on Unstained
cyto_gate_draw(gsSamp,
               parent = "Single Cells",
               alias = c("Live", "Dead"),
               channels = "FL4-AREA",
               type = "interval",
               negate = TRUE)

# Gate Annexin-pos Cells
cyto_gate_draw(gsSamp,
               parent = "Single Cells",
               alias = c("Annexin+", "Annexin-"),
               channels = "FL2-AREA",
               type = "interval",
               negate = TRUE)

# display tree
cyto_plot_gating_tree(gsSamp)

cyto_plot_gating_scheme(gsSamp)
Error in cyto_gate_convert.rectangleGate(z, channels) : 
  Supplied gate must contain co-ordinates in the supplied channel.
In addition: Warning messages:
1: In par(pars) : argument 1 does not name a graphical parameter
2: In par(pars) : argument 1 does not name a graphical parameter

Expected behavior
It would plot all the gates involved, and it shcoul not end in an error.
