[Vue TS Plugin] The tsconfig selected for root file and external file is inconsistent about typescript HOT 1 CLOSED

This is working as intended per configuration.

When we lookup apps/web/tsconfig.json: main.ts is marked as root of referenced from referenced directly but part of referenced project = { "key": "c:/temp/vite-issue-1815/apps/web/src/main.ts", "value": "c:/temp/vite-issue-1815/apps/web/tsconfig.app.json" } but not app.vue because the config file for referenced projects isnt returning the vue files.. They are part of projects as external files but not as "config" file names which results in discrepancy in how ts files are treated vs vue files.

This can be fixed by plugin by setting extraFileExtentions through ConfigureRequest : https://github.com/microsoft/TypeScript/blob/main/src/server/protocol.ts#L1496

Eg i passed this command to server before opening the file and app.vue works same as main.ts

{ "seq": 1, "type": "request",      "command": "configure", "arguments": { "extraFileExtensions": [{ "extension": ".vue", "isMixedContent": false, "scriptKind": 7 }] }}

from typescript.
