fix(60887): Incorrect Formatting on if (a) try {} finally {}

Fixes #60887

I'm suspicious about this just because all of the other code in this switch case are only checking syntax kind or position info, not node equality.

@jakebailey thanks for the feedback. I found that in this case, the finallyBlock should not be handled as a child of the try block to ensure the correct delta calculation

TypeScript/src/services/formatting/formatting.ts

Line 624 in 5170645

const delta = SmartIndenter.shouldIndentChildNode(options, node) ? options.indentSize! : 0;

There are other places where we handle the finallyBlock in a similar way

TypeScript/src/services/outliningElementsCollector.ts

Lines 259 to 261 in 5170645

	else if (tryStatement.finallyBlock === n) {
	const node = findChildOfKind(tryStatement, SyntaxKind.FinallyKeyword, sourceFile);
	if (node) return spanForNode(node);

I hope that makes sense., if you have any thoughts or suggestions, I’d be grateful to hear them. thanks

How does this bug not affect the try block or the catch block, then? Maybe I'm missing something...

Hey @jakebailey, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/164566/artifacts?artifactName=tgz&fileId=B9186007CBA01B4F34C25858EFDA94F805D5C7AC878A1E404ABE28F5E4F85F1902&fileName=/typescript-5.8.0-insiders.20250118.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;
