Debug issue after updating to Grails 5: lose the ability to set breakpoints again after run

This ticket is based on support feedback.

I am having issues where the Debug gets out of sync and I cannot set breakpoints. After I restart the debugger then I can set breakpoints. After I run my code once, I lose the ability to set breakpoints again. I have noticed this behavior since I updated to Grails 5 roughly a year ago but I kept hoping IDE updates would resolve the issue. This hasn't happened yet and its driving me crazy and need to get this resolved. I have attached screen recording that demonstrates the issue.

I seem to notice this issue only happen when Groovy closures are involved and even more with multiple nested closures. I am running code that does not have closures they I have yet to see this issue. Please let me know if any additional information is needed

## **Scenario:**

1. Set breakpoints

2. Run debug session

3. When debug session is finished, click to the breakpoint from step 1

**Expected result:** you can click to the breakpoint to remove and add it again.

**Actual result:** the breakpoint becomes [invalid](https://www.jetbrains.com/help/idea/using-breakpoints.html#breakpoint-icons) and you can't add it again.

If right-click to the invalid breakpoint:

Start by reproducing the scenario in IntelliJ IDEA 2023.2.2 with Grails 5 code containing nested Groovy closures: set breakpoints, run a debug session, and inspect them afterward. Done means the original breakpoints remain valid and can be removed or added again after the session ends.
