Change Details

**List of steps to reproduce** (step by step, including full links if applicable): * Install VisualEditor on a plain vanilla MediaWiki site * Pick a page, and edit it with VisualEditor several times in a row, as rapidly as you can. Click Edit, make a small change, click Save, wait for the save to complete, and repeat. **What happens?**: This error dialog appears: //Revision IDs returned by the server do not match (document: 4525, metadata: 4526)// with buttons //Cancel// and //Try again//. I'll attach a screenshot so you can see the state VisualEditor is in. The two integers vary, of course. **What should have happened instead?**: No error dialog **Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.**: MediaWiki 1.37.1 VisualEditor 0.1.2 **Notes**: * I tested this on a plain vanilla wiki with no caching, and also a more optimized wiki with memcached. Same error.
