[BUG] Can't edit grades

[mrmbernardi]

Describe the bug
When editing grade ECTS and weighting, the keyboard appears but it is not possible to edit the content. It's not really shown in my screen recording but sometimes the caret does appear briefly before disappearing. Pressing and holding also gives weird behaviour, like a context menu appearing with options like "Paste" which don't change the text at all, and a marker showing up where the caret should be.

To Reproduce
Steps to reproduce the behavior:
Try to edit ECTS and weighting in the grades window.

Expected behavior
Can edit grade ECTS field and weighting
