Describe the issue you are experiencing

Some entities do not show up in selectors or in searches when using 'e' on a dashboard. I have an entity "Master Bathroom Ventilation Fan On Threshold" with an id input_number.master_bathroom_ventilation_fan_on_threshold which is just a normal helper input number.

Searching with 'e' reveals just a full list (should that be an empty list? seems like a bug when nothing matches to return all entities)

When searching from an entity input it incorrectly shows no results (which I prefer when there's no match to the behavior above).

It does show up in some places like when adding a card "by entity"

Describe the behavior you expected

I expect to find the entity in all places. Beyond that when there is no match found I expect a result of "no matches" rather than an unfiltered list.

Steps to reproduce the issue

1. Create an input number (or it seems like any other helper) with the name "Master Bathroom Ventilation Fan On Threshold"
2. Search for that entity
