Invalid reference to "oldModuleMap" and "specifier" in "merge existing and new import maps"

[shannonbooth]

What is the issue with the HTML Standard?

Merge module specifier maps introduced in #10528 refers to "oldImportMap's" without any proceeding definition to say what "oldImportMap" is.

I also noticed that step 3.1.1.1.1.2 says "Remove scopeImports[specifier].", I believe this should instead be: "Remove scopeImports[specifierKey]."
