fix: edit dialog accessiblity validation logic available in shadow dom

[nayounsang]

Description

close #3484

• Fixed accessibility validation logic for Dialog Title and Description.
  • Passing ContentRef props <TitleWarning titleId={context.titleId} contentRef={contentRef} />
  • Validate in the Content contentRef.current?.querySelector(#${titleId});
• Strictly check if it is inside Content as the error message says
• Compatible with Shadow DOM (The document-based logic of the existing logic does not work when used in shadow DOM)
• (Performance improvement is also expected as it checks a narrow range inside the content. But I didn't think it was important so I didn't bother measuring it haha)

This is test code. All passed. But I will include it if you give me feedback that it needs to be committed.

    describe('when in Shadow DOM', () => {
      let shadowRoot: ShadowRoot;
      let shadowContainer: HTMLElement;

      beforeEach(() => {
        // make shadow root
        const host = document.createElement('div');
        document.body.appendChild(host);
        shadowRoot = host.attachShadow({ mode: 'open' });

        // render dialog in the shadow root
        shadowContainer = document.createElement('div');
        shadowRoot.appendChild(shadowContainer);

        cleanup();
        rendered = render(
          <Dialog.Root defaultOpen>
            <Dialog.Trigger>{OPEN_TEXT}</Dialog.Trigger>
            <Dialog.Overlay />
            <Dialog.Content>
              <Dialog.Title>{TITLE_TEXT}</Dialog.Title>
              <Dialog.Description>Description</Dialog.Description>
              <Dialog.Close>{CLOSE_TEXT}</Dialog.Close>
            </Dialog.Content>
          </Dialog.Root>,
          { container: shadowContainer }
        );
      });

      afterEach(() => {
        document.body.innerHTML = '';
      });

      it('should not show any errors when title is present in Shadow DOM', () => {
        expect(consoleErrorMockFunction).not.toHaveBeenCalled();
      });

      it('should not show any warnings when description is present in Shadow DOM', () => {
        consoleWarnMockFunction.mockClear();
        expect(consoleWarnMockFunction).not.toHaveBeenCalled();
      });
    });

titleId needs to be sanitized in case it contains : - which is the case for react <19

Suggested change

	const hasTitle = contentRef.current?.querySelector(`#${titleId}`);
	const hasTitle = contentRef.current?.querySelector(`#${titleId.replaceAll(':', '\\:')}`);

could also use CSS.escape instead of manual string replace
