I have php that includes javascript (it uses echo() to output javascript code). When I attempt to set a breakpoint in a javascript function in the php file, the breakpoint appears as a red hollow circle with a yellow caution sign. Hovering my mouse over this displays the message, "The breakpoint will not currently be hit. Unbound breakpoint." I can set breakpoints in other files.
I am running PHP Tools version 1.72.17587 and VS 17.5.3. I tried reinstalling PHP Tools. I tried manually shutting down and restarting VS.
I am pretty sure I could set breakpoints on this code in the past (I can't imagine how I could have written the code without debugging it).
