Is it possible to programmatically force the mouse cursor to "reset" based on what's under it?

Note the the mouse cursor generally changes when moving across certain boundaries, i.e. in a web browser when you move the cursor over a text form, it changes from an arrow to a caret, and vice versa when you exit the text area. [This Chrome bug](https://issues.chromium.org/issues/430116472) describes an issue with fullscreen Chrome instances where the cursor gets into a bad state in a predictable way. Assume (hypothetically) that there is some OS-level command that I can issue that essentially does "check what kind of thing the cursor is over, and reset the cursor to the right type". Then as a workaround for the bug, I could write an automator app that fires that command a few times per second. Does the hypothetical command exist? EDIT: I've added a workaround that I discovered, to the bug linked above.
