• Subsystem: repl?

What steps will reproduce the bug?

1. start the node repl: node

2. type a few numbers in but don't press enter, e.g. 1<backspace>2<backspace>3<backspace>. no eager-eval should be printed

3. type a number followed by a decimal point e.g. 1.<backspace>. the eager-eval should be immediately triggered. When you type in 1 again (without the decimal point), you'll see eager-eval prints 1, but only for 1, not any other numbers

4. Type a different number followed by a period e.g. 6.<backspace>. Now eager-eval will only print when you type 6

How often does it reproduce? Is there a required condition?

Always. None.

What is the expected behavior?

eager-eval should print the number regardless of the decimal point.

What do you see instead?

eager-eval only prints the number you typed if just before you typed it, you typed the number with a decimal point

Additional information

Introduced in version 13.4.0 and 12.17.0. Looks like it's caused by #30811 (which introduced the feature in the first place)
