Complexity: 3

This milestone we have introduced data breakpoints to VS Code. Currently Mock debug is the only debug extension that supports this. So, install the Mock Debug extension and start debugging a markdown file. Verify:

• You can set new data breakpoints using the context menu in the VARIABLES view
• Data breakpoints get shown in the breakpoints view
• Depending on the canPersist flag of the data breakpoint the breakpoint either gets stored when the session ends or they get removed
• Once a data breakpoint is set for a global mock debug variable, and the name of that variable appears in the .md file the breakpoint gets hit
• Data breakpoints can be disable / enabled / removed like all other breakpoints
