Fixes #18203
Problem
When using
normalizeDepth: 10withcaptureConsoleIntegrationenabled, Vue VNodes in console arguments would trigger recursive warning spam. Accessing VNode properties during normalization would trigger Vue's reactive getters, which emit console warnings. These warnings would then be captured and normalized again, creating a recursive loop that could generate hundreds of warnings.Note that this only happens in
devmodeSolution
Changed
isVueViewModel()to detect Vue 3 VNodes (__v_isVNode: true) in addition to Vue 2/3 ViewModels. VNodes are now identified early in the normalization process and stringified as[VueVNode]before their properties are accessed, preventing the recursive warning loop.Some of the properties on the
VNodecan also be reactive, so it can incorrectly add those to a watchEffect or a render function reactive dependencies when accessed by the normalizer.Changes
packages/core/src/utils/is.ts: Added__v_isVNodecheck toisVueViewModel().packages/core/src/utils/normalize.ts: Distinguish VNodes from ViewModels in output ([VueVNode]vs[VueViewModel]).I couldn't reproduce this exactly in a test with a real vue component, but verified it fixes the reproduction example.

As a Vue developer I don't think the loss of information here would help debug anything.
