stale element reference: stale element not found

🐛 Bug Report

Running on Windows 11, 4.0.1 Beta 10.

If I run the test script using the Chrome plugin 3.17.2, the VerifyText works fine. If I run using the latest IDE, I get

The text I am looking for is a message generated by a datatable after an AJAX call. The call takes < 150ms. The message stays on the screen indefinitely.

The first 20 lines of the test script run fine. If I use the 'select element' function and reselect the text in the browser, it still fails.

To Reproduce

Create a page and have a DataTable from https://datatables.net on it and make an AJAX call that returns no data.

Expected behavior

VerifyText to look at the message and return successfully and without error. The browser plugin running the same .side file returns successfully.

@andyp05 - For my own personal interest, do you primarily use code-export? I'm always interested in the pain points of people who have code export workflows.

I think in v3 browser, there may be some level of durability that doesn't exist here. I'd recommend swapping this command for waitForText in v4, which has a lot more durability built into it. In my mind, this is how the variants of the commands work (feel free to correct me because idk why there are three variants of this command in the first place):

assert text - checks immediately with a very low level compare function. non polling, non async
verify text - literally the exact same as assert, i have no idea why both of these variants exist
wait for text - The Right Command. Tries and catches and retries for a duration all the way down.

Replaced 'Verify Text' with 'Wait for text' and it worked. Thanks for your help.
