Timed out retrying: Maximum call stack exceeded when typing into Salesforce Lightning Components

[jennifer-shehane]

Current behavior:

When attempting to type into certain elements from Salesforce lightning components, an error is thrown like below:

CypressError: Timed out retrying: Maximum call stack size exceeded

Similar to previous issue that was resolved in 4.1.0 when doing visibility checks on elements - likely we are naively doing another check during type that is not considering the shape of elements generated in Salesforce Lightning Web Components #4373

Desired behavior:

Should not throw Max call stack error

Test code to reproduce

Pending

Versions

Cypress 4.1.0

I was able to track this Max call stack being thrown from the getFirstStickyPositionParent method. Similarly to the previous visibility check, it is iterating over the element without checking if $el[0] exists first. So, goes into an infinite loop.

https://github.com/cypress-io/cypress/blob/develop/packages/driver/src/dom/elements.ts#L917:L917

Likely there are other places where this check is insufficient still, so I'll take a look at some other instances and hopefully extract out this check into a broader method of 'checkExistence' and/or 'checkIfHtmlBodyOrDocument'.

Now comes the hard part of isolating a failing test case for the PR.

Getting past the max call stack error, there is a separate error trying to type into a textarea in Salesforce Lightning Components.
