Error exporting to .sif (Synfig Animation) with currentColor

Summary:

I get the following error when trying to export this SVG (https://kde.org/stuff/clipart/logo/plasma-logo-monochrome.svg) to .sif:

Traceback (most recent call last):
  File "/snap/inkscape/10512/share/inkscape/extensions/synfig_output.py", line 1485, in <module>
    SynfigExport().run()
  File "/snap/inkscape/10512/share/inkscape/extensions/inkex/base.py", line 231, in run
    self.save_raw(self.effect())
  File "/snap/inkscape/10512/share/inkscape/extensions/synfig_output.py", line 1158, in effect
    layers += self.convert_node(node, doc)
  File "/snap/inkscape/10512/share/inkscape/extensions/synfig_output.py", line 1194, in convert_node
    layers = self.convert_path(node, d)
  File "/snap/inkscape/10512/share/inkscape/extensions/synfig_output.py", line 1390, in convert_path
    color = extract_color(style, "fill", "fill-opacity")
  File "/snap/inkscape/10512/share/inkscape/extensions/synfig_output.py", line 1098, in extract_color
    c = inkex.Color(style[color_attrib]).to_rgb()
  File "/snap/inkscape/10512/share/inkscape/extensions/inkex/colors.py", line 248, in __init__
    space, color = self.parse_str(color.strip())
  File "/snap/inkscape/10512/share/inkscape/extensions/inkex/colors.py", line 352, in parse_str
    raise ColorError(f"Unknown color format: {color}")
inkex.colors.ColorError: 'Unknown color format: currentColor'

The error happens no matter if I use Snap or Flatpak. It also happens on another computer.

Steps to reproduce:

• open Inkscape with provided SVG
• Select "Save as..."
• Select the .sif format
• Type a name
• Hit save.
