Styling breaks at deeply nested scope

[dsl101]

Again, I'm unsure if this is a syntax issue or a theme issue, but here's the block of code showing the problem. Highlighting from the permission variable inside the second promise handler starts to go wrong, and never really recovers:

The scope data for the first (correct) permission is:

Scope:                         text.html.vue
                               source.js.embedded.html
                               source.js
                               meta.export.js
                               meta.object-literal.js
                               meta.object-literal.js
                               meta.function.js
                               meta.block.js
                               meta.conditional.js
                               meta.block.js
                               meta.for.js
                               meta.block.js
                               meta.switch.js
                               meta.block.js
                               meta.block.js
                               meta.conditional.js
                               meta.block.js
                               meta.function-call.method.js
                               meta.group.js
                               meta.function.declaration.js
                               variable.parameter.function.js
Fg Name:                       Member variables
Fg Scope:                      variable.language, variable.other.member, variable.parameter, variable.other.readwrite.member, entity.other.attribute-name
Bg Name:                       background

tmTheme File:                  Packages/User/Monokai++.tmTheme

and for the second (incorrect) one it's:

Scope:                         text.html.vue
                               source.js.embedded.html
                               source.js
                               meta.export.js
                               meta.object-literal.js
                               meta.object-literal.js
                               meta.function.js
                               meta.block.js
                               meta.conditional.js
                               meta.block.js
                               meta.for.js
                               meta.block.js
                               meta.switch.js
                               meta.block.js
                               meta.block.js
                               meta.conditional.js
                               meta.block.js
                               meta.conditional.js
                               meta.block.js
                               meta.function-call.method.js
                               meta.group.js
                               meta.function.declaration.js
                               variable.parameter.function.js

Can you tell what's going wrong here?
