I opened a Pull Request with the following: 🔄 1 test added. 🔄 Test UpdatesI've added 1 tests. They all pass ☑️
No existing tests required updates. 🐛 Bug DetectionPotential issues found in the following files:
The error is raised by the code in Registry.execute_action when it calls the action function. Although the test calls execute_action with a “browser” keyword argument (and so the merged parameters should include browser), the function ends up not actually receiving that argument. In other words, the extra browser parameter is either being dropped or not passed correctly when calling action.function(**validated_params.model_dump(), **extra_args). This causes the underlying async function (test_action_with_browser) to be invoked without its required “browser” parameter, triggering a TypeError. Thus, the registry’s implementation of execute_action is buggy in how it handles and passes extra keyword arguments to the action function. 🛠️ Test Results1/8 tests passed tests/test_dropdown.py View errortests/test_dropdown.py:20: in <module>

This PR improves the DOM processing functionality. Instead of saving DOM in a tree structure, it saves elements to a hash map and keeps the pointers for rewiring in Python.
It's a drop in replacement that changes no interfaces.
Additionally, it improves the calculation of the DOM elements in the JS eval script by ignoring the added indicator elements.
