Suggested reviewers: Merge Risk: 🟡 Moderate · up to The font picker can apply a previously selected font to text typed at an unrelated caret location after moving across non-text editor content. Some related UI-test selectors are also coupled to implementation details, reducing regression coverage stability.

- Around line 168-180: Update Test 6 after editor.selection.setCursorLocation to
type new text at the caret before asserting the result. Assert specifically that
the inserted text does not have a courier font-family, ensuring the pending-font
clearing behavior is exercised.
- Around line 91-92: Augment the Cypress Window type with an ambient tinymce
property using the installed TinyMCE type, so the win.tinymce access in the
cy.window callback type-checks under strict mode. Reuse the existing TinyMCE
type import or declaration and avoid changing the test behavior.

Use stable data- hooks for the new application-owned locators.*
The cited non-TinyMCE locators use CSS classes, name, and role selectors. This violates the Cypress convention for this path and couples tests to implementation details. Add stable data-testid or data-cy hooks to application-owned controls and use those hooks here.
For TinyMCE controls, use a stable data-mce-* hook only when one exists. Retain ARIA selectors for TinyMCE dropdown items when no such hook exists; data-mce-name does not apply to those items.

Description
Add TinyMCE's built-in Font Family control to the classic Rich Text Editor toolbar. The list is TinyMCE's web-safe fonts, minus dingbats, with Default mapped to the existing Times look so current apps do not restyle.
A collapsed caret applies the font to the next typed text, not the current paragraph. Moving the caret (click, arrows, Home/End) drops that pending pick so it is not applied at an unrelated location.
