Issue with element_path() in {ggplot2} version 4.0.0 #24
Description
When I try to run ggpath::element_path() with a url to place a ggplot tag on my graphic, the code initially runs fine until I try to render the plot, at which point it spits out the cannot coerce error below. Prior to the updates to both {ggplot2} and {ggpath}, the below code ran fine. Now it is triggering an error.
Additionally, when trying to use nflplotR::element_nfl_logo() to replace the names of teams on the y axis of a bar chart, it now only deletes the team name text, but doesn't replace them with images.
