- Various telemetry methods now need an object to be passed in in order to keep them seperate e.g. if the inspector is opened in tab 1 a timer is started. If an inspector is opened in tab 2 the same timer is restarted. Closing tab 2 would then erase the timing event invalidating the timer in tab 1. - We no longer need to preface telemetry calls with category "devtools.main" because this is the only category we will be using. - There are some changes to `devtools/client/debugger/new/dist/vendors.js` and `devtools/client/debugger/new/src/utils/telemetry.js` that need to be ported to the debugger at the same time as landing this.

/**
|
|
* WeakMapMap is a weakmap collection dual-keyed using an object and a string.
|
|
* This is useful for keeping data compartmentalized e.g. grouped by tab.
|
|
*
|
|
* It's name comes from the internal structure which maps a WeakMap to a map,
|
|
* which contains the target data.
|
|
*
|
|
* Usage:
|
|
* const myWeakMapMap = new WeakMapMap();
|
|
* const key = { randomObject: true };
|
|
* myWeakMapMap.set(key, "text1", "Some value1");
|
|
* myWeakMapMap.set(key, "text2", "Some value2");
|
|
* myWeakMapMap.get(key, "text1"); // Returns "Some value1"
|
|
* myWeakMapMap.get(key, "text2"); // Returns "Some value2"
|
|
* myWeakMapMap.has(key, "text1"); // Returns true
|
|
* myWeakMapMap.has(key, "notakey"); // Returns false
