Hello
Recently we noticed a problem with our combo-box dropdown. Essentially, when we manually cleared out the value after searching the combo-box, the dropdown would not go back to showing all of the combobox items - but rather the results from the last search. The attached picture shows the problem - in it, you can see we're shown the 'Fanta' option in the dropdown, although theres no longer a 'f' in the search bar, and theres other items in the combobox.
To replicate this - you can go to the codepen example in https://www.bryntum.com/docs/grid/api/Core/widget/Combo and you can change the existing drink combobox to look like
// combo with string items
new Combo({
items : ['Fanta', 'Loranga', 'Jaffa', 'Zingo', 'Orangina'],
label : 'Items as strings',
keyStrokeFilterDelay: 300,
appendTo : document.body,
style : { marginRight : '.5em' }
});
As you can see - the only difference is adding a keyStrokeFilterDelay of 300. Then just type 'fan' into the combo-box. Observe how only Fanta appears. Then delete all the letters by repeatedly hitting the delete key. Observe how after that - only Fanta appears again as an option. This seems incorrect - you would expect all the options to reappear after the search text has been manually cleared.
Would someone be able to look at this?
Thanks!
