EarlGrey 2.0 | EarlGrey hangs when attempting to clear a webview edit text

I'm currently performing a query with:
EarlGrey.selectElement(with: grey_allOf([grey_accessibilityLabel("abcxyz"),
grey_accessibilityTrait(UIAccessibilityTraits.staticText)]))
.perform(grey_replaceText(textToType))
where the hierarchy dump shows a few items that match the AX.label and one that has the expected accessibility trait:
Partial (focused) hierarchy dump

- | | | | | | | | | |--
- | | | | | | | | | | |--
- | | | | | | | | |--
- | | | | | | | | | |--

however, strangely enough, this hangs on a call in: + (void)grey_setText:(NSString *)text onWebElement:(id)element {
[element accessibilityLabel], [element accessibilityLabel]]; - https://github.com/google/EarlGrey/blob/earlgrey2/AppFramework/Action/GREYActions.m#L471

From what I can tell, this is likely an EarlGrey issue. I verified I have the latest version of GreyActions.m released.
