Regression Ctrl+Left/Right doesn't jump to upper case letters

It stopped working in the Search/Rename/Replace input boxes, where this feature is very important because if you want to change/rename some name/variable, you very often need to change only a part of the name, which means you need to select this part first.

This started in qtc13, previously was very easy to rename only some part of a word, eg. BindingsMapType -> BindingType, I hit Ctrl+Left, Ctrl+Shift+Left, Del (if the cursor was at the end). Now I need to use a mouse to select it or use arrows and select letters manually, eg. Left, Left, Left, Left, Shift+Left, Shift+Left, Shift+Left, Del.

The current behavior is Ctrl+Left/Right jumps to the beginning/end of the input box (it still stops at spaces, _, -, ...).

Now I tried in qtc12 and there it works in all input boxes, eg. the Search input box in Settings, or Filter input box in the Application output view or Test Results view, so it was disabled globally everywhere, can we revert the old behavior?
