It work fine in 51 version. But in fact the data can be retrieved, for example, input number 2, it will still be prompted 23 in list. So I'm not sure if it is intentional, or is it really a bug.

I don't understand. It does not have a patch.

I misunderstood the meaning of that bug. The problem still exists.

Dunno how you feel about the nomaxresults attribute. I could also just extend the binding and override the property. I don't have a preference.

Thanks. I guess this wfm. I forget if there was a reason we were avoiding extending the binding? It seems like that would be the cleaner solution but I don't know if it's worth the potential wasted time if it doesn't work out. So I only slightly prefer extending at this time (especially given we're both busy).

Honestly, just laziness - as you say, we're busy with other stuff.

I'll file a follow-up bug to extend the binding as a solution instead.

Bug 1352620 - Don't have a hardcoded limit of 20 items in AutoCompletePopups.

Approval Request Comment
[Feature/Bug causing the regression]:

Bug 1296638

[User impact if declined]:

Autocomplete results, or datalists will have a hard-coded cap of 20 entries.

[Is this code covered by automated tests?]:

Yes, autocomplete and datalist has automated tests. Unfortunately, none of them caught this particular bug.

[Has the fix been verified in Nightly?]:

I have manually verified it.

[Needs manual test from QE? If yes, steps to reproduce]: 

No, I don't think so.

[List of other uplifts needed for the feature/fix]:

None.

[Is the change risky?]:

No.

[Why is the change risky/not risky?]:

We're bypassing a hardcoded result limit in the richlist autocomplete popup in a way that is pretty straight-forward.

[String changes made/needed]:

None.

Bug 1352620 - Don't have a hardcoded limit of 20 items in AutoCompletePopups.

Fix a regression that <datalist> can only suggest the first 20. Beta54+. Should be in 54 beta 11.

Setting qe-verify- based on Mike's assessment on manual testing needs.

Is this something we should consider backporting to ESR52 or should we let it ride the trains?

I think it's a safe uplift, but I wouldn't call it security critical, which (I imagined) was what we did ESR uplifts for. Does that help clear it up?
Flags: needinfo?(mconley)
Patches for severe regressions can also be considered for ESR52, just not sure whether this meets the bar or not.
Flags: needinfo?(mconley)
I wouldn't call this severe, tbh. It's an annoying bug, but we shipped it in 53, and didn't feel cause to do a dot release for the fix or anything.

So I think we should leave it be.
