User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0

Steps to reproduce:

Set a break point in a function
Inspect arguments by hover

Actual results:

Says undefined

Entering "report" in the console also says defined, when isn't

Expected results:

Should say the same as when console.log( arguments )

Second screen shot showing issue not confined to tool tip, something is broken in the debugger inspector itself

Entering "report" and "arguments" into "Watch expressions" reports "report" as "(unavailable)" - different to the tool tip. "arguments" as watch expression works fine.

Our code is minified with Browserify if that helps
