775854 - Form autocomplete suggestions for "example " (with space) includes "example" (without space)

Status: RESOLVED INVALID

(Toolkit :: Form Manager, defect, P3)

Description

[Chris Peterson [:cpeterson]]

This example assumes your form autocomplete history includes an entry for the word "cat".

STR:
1. Load any page with a text input form. I like using the Firefox Mobile Support page.
2. Type "cat"
3. See "cat|"
4. See autocomplete suggestions include "cat"
5. Type space
6. See "cat |"

AR: Autocomplete suggestions still include "cat"

ER: Autocomplete suggestions should not include suggestions shorter than the current text

This is reproducible on desktop, so it's an issue with the form autocomplete service, not our IME code.

Also, is it really so bad to have a suggestion show if you have additional whitespace in your input box? Sometimes this might be preferred if you copy/pasted a string and accidentally included extra whitespace.

This is intentional as part of form awesomecomplete where we match on tokens/words instead of just prefix matching. See bug 446247 and

I can see how this might be useful, such as knowing that the phrase you've typed is already in your form autocomplete history.

I understand now that we're matching words, not whitespace, but it still feels a little strange that the shorter suggestion is still displayed after I have typed a space as I prepare to type a longer phrase.

But if this is intentional, I can just close this bug as INVALID.
