Changes in Chrome 155 may cause cdp.dom.enable() to start failing.

It might only be used in one area:

SeleniumBase/seleniumbase/undetected/cdp_driver/element.py

Line 1271 in abf6193

await self.tab.send(cdp.dom.enable())

The easy fix is to suppress any exception that would be raised from calling that.
