When running a mochitest on my Windows workstation, it sometime hits the following assertion. I use ATOK (IME) that is a11y application. So could you change this assertion to warning or fix this assertion?
```
already_AddRefed<IAccessible> AccessibleWrap::GetRemoteIAccessibleFor(
const VARIANT& aVarChild) {
...
DebugOnly<HRESULT> hr =
disp->QueryInterface(IID_IAccessible, getter_AddRefs(result));
MOZ_ASSERT(SUCCEEDED(hr));
```
Stack is the following.

When running a mochitest on my Windows workstation, it sometime hits the following assertion. I use ATOK (IME) and/or Microsoft IME that is a11y application. So could you change this assertion to warning or fix this assertion?
```
already_AddRefed<IAccessible> AccessibleWrap::GetRemoteIAccessibleFor(
const VARIANT& aVarChild) {
...
DebugOnly<HRESULT> hr =
disp->QueryInterface(IID_IAccessible, getter_AddRefs(result));
MOZ_ASSERT(SUCCEEDED(hr));
```
Stack is the following.
