When using ctrl+a, ctrl+c, ctrl+x and ctrl+v the respective letter (a,c,x or v) will be typed this causes:
ctrl+a replaces the entire text with just a and removes the selection
ctrl+c replaces the selected text with c but correctly copies the text
ctrl+x is identical to ctrl+c
ctrl+v appends a v to the end of the text
This appears similar to MC-121278 but should be a different issue as I can recreate the issue when using US layout
