1777460 - Support "this" parameter for "script.callFunction" command

Status: RESOLVED FIXED

(Remote Protocol :: WebDriver BiDi, enhancement, P1)

Description

[Julian Descottes [:jdescottes]]

https://w3c.github.io/webdriver-bidi/#command-script-callFunction supports an optional this argument which should be used as the scope of the function call.

If this parameter is not null, set this object to the result of trying to deserialize local value given realm and this parameter.

Blocking on Bug 1770492 because handling thisParameter is similar to arguments handling.
Tentatively blocking on Bug 1770736 (strong object references), but in theory we could support a thisParameter using a serialized remote value which is not a handle (eg a serialized object). This is very much an edge case, but this is an option according to the specs.
