Improvements

TinyMCE 8.3.2 also includes the following improvement:

`uc-video` elements are not refreshed on undo/redo actions

Previously, undo and redo operations rewrote the entire editor content, causing embedded uc-video elements to be rewritten and unintentionally refreshed, which disrupted playback and user experience. This behavior affected any content containing uc-video, as media elements were reloaded even when unrelated changes were undone or redone. The undo/redo mechanism has been updated to align with the existing iframe handling logic so that, when uc-video elements are present, only the modified portion of the content is refreshed rather than the full editor content. As a result, uc-video elements now remain stable and are no longer refreshed during undo or redo actions in TinyMCE 8.3.2.
