* jsdoc ?Type adds optionality to parameters Chrome devtools expects that parameters with type `?T` (or `T?`) add null to `T` and optionality to the parameter. Previously it only added null to the type. Currently the PR does *not* add undefined to the type of `T`, which is expected by chrome-devtools-frontend, but is inconsistent with typescript's rules. The implementation achieves this inconsistency by exploiting the fact that checking the signature adds optionality and checking the parameter adds `undefined`. * Update chrome-devtools-frontend baseline * Add optionality only for jsdoc postfix= * Skip jsdoc prefix types in isJSDocOptionalParameter Previously isJSDocOptionalParameter was incorrect for types like `?number=`, which are optional but have JSDocNullableType as their root type node.
