Wrong peripheral values are shown when expanded for the first time

Type: Bug Report

• OS and Version: Windows 10 Enterprise 22H2
• VS Code Version: 1.91.1
• Extension Version: 1.4.6
• Target Device: Cortex-M33-based MCU

The first time XPeripherals view is expanded, it does not display proper register values. "Refresh" button does not help either. As soon as any action (step, continue-pause) is performed, the view is refreshed and shows proper values.

Steps to reproduce the behavior:

1. In the firmware store value of some peripheral register, lets call it "DAC_VAL" into the variable.
2. Set breakpoint next to the variable from step#1.
3. Launch debug session, resume the core until it reaches your breakpoint.
4. Expand XPeripherals view, then find DAC_VAL reg
5. Compare value of peripheral register with:

• DAC_VAL value stored into the variable (step#1) and observe mismatch
• debug console logs displaying values read by extension and observe mismatch

7. Press the "Refresh" button and observe it does not change DAC_VAL
8. Read DAC_VAL by GDB 'x' command and observe GDB's value differs from XPeripherals
9. Perform single step and observe XPeripherals is refreshed and now shows proper DAC_VAL value

Expected behavior
XPeripherals shows proper values once expanded for the first time
