Customise layout can't distinguish diagonal swipes

### Steps to reproduce I tried making a test layout to have a go at making my own changes. Here's the edits I have ENThumbKey: main: key1_0: topRight: { text: ñ } shifted: key0_0: right: { text: Ê } topRight: { text: È } top: { text: Ę } This layout can type È for some reason, but not ñ, Ê or Ę ### Expected behavior I should be capable of typing the characters I mentioned ### Actual behavior It substitutes ñ for eithe n or m, Ê for È or W, and Ę for È or S. Almost as if it doesn't recognise those directions and is trying to find the nearest other. ### version of the program 5.1.3 ### Android version Android 14 ### Device Samsung A13 ### Other details Nothing else to add ### Acknowledgements - [x] I have written a short but informative title. - [x] I have updated the app to **[the latest version](https://github.com/dessalines/thumb-key/releases/latest)**. - [x] I have searched the existing issues and this is a new one, **NOT** a duplicate or related to another open issue. - [x] This is not a question or a discussion, in which case I should have gone to [lemmy.ml/c/thumbkey](https://lemmy.ml/c/thumbkey) - [x] This is a **single** bug report, in case of multiple bugs I will open a separate issue for each one (they can always link to each other if related) - [ ] I have admitted that I am a clown by having checked this box, as I have not read these acknowledgements. 🤡 - [x] I have filled out all of the requested information in this form.
