1. Focus a textarea.
2. Type some characters. Note that each time you hit a key, the caret becomes visible and the blink timer is restarted. While a key is held, the caret remains visible.
3. Now hit and/or hold the backspace key. The caret isn't forced to be visible for each key event (unlike when other keys are typed). Instead, it continues blinking at its normal rate.

If you're holding backspace to delete a long run of blank spaces, it's impossible to tell where the caret is while it's in the hidden phase of its blinking cycle.

Is there a particular reason we don't immediately show the caret on backspace like we do for other key events?

Also note that this is inconsistent with Views: if I type a bunch of spaces into the omnibox and then hold the backspace key, the caret remains visible while I'm deleting.
