Bug ID: 52113
Summary: VisualEditor - Undo keyboard shortcuts clear undo /
redo history if pressed to often. (And other fun)
Product: VisualEditor
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Unprioritized
Component: General
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Mobile Platform: ---
Tested on Firefox 22 (Monobook) and Chrome 28 (Vector)
Steps to reproduce:
- Open any random page in the visual editor. Personally i used [[Botnet]].
- Add the word "Test" to the page.
- Press Ctrl + Z to undo the edit. Keep pressing till the edit is gone, then
press it once more.
Once you have done this, the Redo button and the Redo shortcut (Ctrl+Shift+Z)
no longer seem to restore the previous edits. Any subsequent edit seems to
reset the undo / redo buttons to an "There were no previous edits" state.
Inconsistent results:
Besides the above result that i can always reproduce using these steps, i have
seen various other results. I have seen each of these at least twice but no
matter what i try, i cannot seem to find any method of reproducing these
reliably.
- An entry in the console log stating "Error: Cannot roll back a transaction
that has not been committed "
- An entry in the console log stating "Error: Range error: Range is no longer
valid after DOM mutation ([WrappedRange("Zz":1, "Zz":1)]) "
- The redo button suddenly inserting "♙" once in Chrome.
- The undo button suddenly inserting an endless steam "♙" in Firefox.
