When renaming a file in Windows, CTRL + Backspace does not delete whole words

The Ctrl+Backspace shortcut for deleting whole words is a feature in most text editors and text inputs. Due to their usefulness, they have become a part of my everyday typing habits. However, in Windows Explorer, when renaming files, Ctrl+Backspace enters a character instead of deleting the previous word. Oddly enough, it's lesser used sibling for deleting the next word Ctrl+Delete works as intended when renaming files.

This is a problem on my work PC, which uses Windows 7. But I recall this being a problem in my home PC, which is ruing Windows 10.

Why does this seemingly universal shortcut not work in this scenario? Are there workarounds (be it first party or third party) to implement this functionality?
