* Fix a couple little issues with the e2e tests

* Fix gizmo e2e tests (it moved) and network health test (it should not be on home page)

* More tweaks to accomodate changes to network health indicator

We made use of two test ID's to make Playwright aware of the state, one
of which was on the icon. Now that we want to normalize usage of the
status bar along a more limited API, that became a not possible. This
just tweaks some test code that relied on that fact.

* Fix lints

* Update snapshots

* Re-run CI

* Update snapshots

* Update snapshots

* Test fixes, label logic tweaks

* Update snapshots

* Update snapshots

* Fix up last few tests hopefully. Relative path syntax failed on windows

* Relative paths are behaving badly on Windows, use the old code here

* Update snapshots

* Update snapshots

* Tweak y-value to work on all platforms, ubuntu didn't like 438

* Fix tooltip and popover alignment on NetworkMachineIndicator

* Remove dire warning comment

* Update src/components/StatusBar/defaultStatusBarItems.tsx

 ## Explicit conversions
 
 You might sometimes need to convert from one unit to another for some calculation. You can do this implicitly when calling a function (see above), but if you can't or don't want to, then you can use the explicit conversion functions in the [`std::units`](/docs/kcl-std/modules/std-units) module.
+
+KCL cannot know about changes to units caused by arithmetic. For example, you may intend for `10in * 25.4` to be the value `254mm` (i.e., `10in` in mm), however, the result of that computation in KCL is `254in`. It is always better to rely on automatic conversion or to use the explicit conversion functions, where possible.
+
+Converting between degrees and radians using π ([`PI`](/docs/kcl-std/consts/std-math-PI) in KCL) is especially prone to this error and so the `PI` constant always requires specifying units of any computation it is used with. E.g., `radius = (circumference / (2 * PI)): number(mm)`.
