Bug 196322 – [iPad] Tapping on a popup form control may not show a popover

• Component: UI Events
• Status: RESOLVED FIXED

[Daniel Bates]

Seen on iOS with ToT.

Steps to reproduce:

Perform on an iPad.

1. Open Settings > General > Keyboards and disable shortcuts.
2. Open Safari and visit <data:text/html,<select><option>First</option><option>Second</option></select>>.
3. Tap the <select> form control.

Then nothing happens. But a popover should open.

Cannot think of a way to write a test for this without going out of my way to programmatically toggle Keyboard Shortcuts :(

This failure looks relevant! Let's look into this (it might just be flaky, but I think it directly exercises -inputView — namely, the branch that returns _dataListTextSuggestionsInputView).

I can imagine an API test for this that invokes -[WKContentView inputView] directly...

Yep, that was my thought too.

And test what? Nil/non-nil? Maybe looking into the test failure above will give me ideas.

Yeah, that's just about all I think a test like that could check :/

Such an API test would probably not be worth the effort.

Didn't even need to try.  Sleep fixes things. This is the line with the bug. We can't early return when we don't have an _inputPeripheral. Why did I make this change? It's because I so want this function to do one thing: only know about input peripheral. The reality is that it can't do one thing we may have a custom view or a data list thingy.
