[FIX] web_editor: focus lost with inline editor

When an inline editor is eg. in a form view, the focus is always stolen
by it.

This is because we trigger a mouseup on the editor to update its
toolbars values and informations.

In 10.0 this was not necessary since the default values were sanely set
when the editor was inside the DOM. In 11.0 the editor is not in the DOM
when this is being done and the info was wrong (eg. NaN for text size).

With this commit, we don't steal the focus and get the default like it
was done in 10.0 instead.

closes #26582
