add go to symbol in the accessible view

demo.mov

fixes #188702

@mjbvz since the accessible view is not attached to an editor pane, the default language features won't work here - thus, this code.

the idea is most of the time the language will be markdown. when it's not, we defer to the provider for symbols IE quick pick items.

vscode/src/vs/workbench/contrib/accessibility/browser/accessibleView.ts

Lines 190 to 195 in a1f77aa

	getSymbols(): IAccessibleViewSymbol[] | undefined {
	if (!this._currentProvider) {
	return;
	}
	const tokens = this._currentProvider.options.language && this._currentProvider.options.language !== 'markdown' ? this._currentProvider.getSymbols?.() : marked.lexer(this._currentProvider.provideContent());
	if (!tokens) {

vscode/src/vs/workbench/contrib/accessibility/browser/accessibleView.ts

Line 223 in a1f77aa

const index = provider.provideContent().split('\n').findIndex(line => line.includes(symbol.info.split('\n')[0])) ?? -1;

do you have a suggestion for a better / more performant / more precise approach?

[mjbvz]

Looks like an ok approach to me. I've also copied @jrieken I believe he's worked more with go to symbol

This isn't going to dismiss the quick pick. Is that expected?

[meganrogge]

accepting one does because of the focus change. escaping the quick pick wasn't handled, but now is #189658

[TylerLeonhardt]

There's a setting called ignoreFocusOut that won't close the quick pick when focus is lost.

As a result this qp won't go away with that setting. I recommend explicitly closing it
