When I create a new topic and I use Control + Enter to save, I get the "data you have entered may not be saved" prompt unnecessarily.
Steps to Reproduce:
- open https://tildes.net/~test/new_topic
- add some text in Title and Text fields
- press Control+Enter simultaneously
- You will see the popup for unsaved data, however the post was actually created.
When using button press of Post Topic, this does not occur and everything is happy. Pressing Control + Enter should have the same result.
