In the 2021 update, I cannot pan the canvas with spacebar while I'm using the lasso tool (actively drawing a line).
In the 2020 version, holding spacebar would temporarily turn the lasso tool into the hand tool, allowing for easy panning without losing the lasso selection. It was very handy for readjusting my hand during a long selection, or simply seeing more of my canvas as I'm selecting.
This must surely be a bug? Please fix this! It's vital to my workflow!
