Describe the bug

I can reproduce an infinite loop during HMR. I have located the loop inside deepEqual function introduced in (#258 and #334). It seems to appear when importing third-party library (here radix-vue / vue) because it recursively walk through the AST of the library components / TS definitions (non-project file).

Related issue #350.
