Mention control not working in release version 31.2.18

[Frederik Gysel]

Dear,

See stackblitz: https://stackblitz.com/edit/ivh9kj-ta6ggj?file=index.html

The mention control popups up when typing for example '@a' but then immediately disappears.

That's the case when using version 31.2.18.
If you change the version in 'index.html' to 24.2.6 the behaviour is correct: after typing '@a' the popup with results found remains visible.

(See attached screenrecording)

Thanks for checking this bug in version 31.2.18.

Frederik

Release Notes : https://ej2.syncfusion.com/javascript/documentation/release-notes/32.1.21?type=all#mention

Root cause :

Previosly ,filtering was always delayed when the query string was not empty and a debounce delay was set, which caused the popup to close unexpectedly when the minimum length was greater than zero.
