I have a few source files which have a peristent breakpoint: no matter how many times I un-check the breakpoint, dirty the file, and save it, the breakpoint comes back. (2019 R1, but it's been a bug for a long time).
I can toggle the breakpoint off, and the IDE will respect that, but only for the current session. Once I re-load the project, it returns.
Where are breakpoints saved and how can I nuke it for good?
