[html] Mirror cursor devolves into multi-cursor when undoing (ctrl-z) #87732
Description
Issue Type: Bug
- Open html document and add a tag
<div></div> - Place cursor at the end of the open tag and add a space
<div ></div> - Undo (ctrl-z) once adds a space to close tag (unexpected, but probably an implementation detail of the space special case 🤷♂)
<div ></div > - Undo (ctrl-z) twice removes the space from the end of both tags
<div></div> - Add a space and start typing
<div class="aClass"></div class="aClass">
Expected:
<div class="aClass"></div>
Basically, after the second undo, you're left with a normal multi-cursor. Even if you move the cursor around the document and keep typing the multi-cursor follows.
