Doesn't repo for me with the latest version. Possibly an issue with one of the TS builds but I don't recall seeing this in the past few weeks either

[matvejs16]

I haven't mentioned that this issue happens only in Vue project files, and that's not only in .vue file, but in .ts files also, idk maybe that's something wrong with Vue typescript

Thanks. Vue support comes from the Vue extension, which can sometime also interfere with features in normal TS files. Please file an issue against your Vue extension for this
