The bug

This is a similar problem as the namesake, MCPE-18376. When typing or removing text inside the Creative mode search tab, the text can be slow to change or update, especially when there's a lot of it, and more so if text is modified towards the start of the search query.

What I expected:

For my changes to the text inside the search query to not cause such a delay.

What happens:

There is a noticeable delay with adding/removing characters.

Reproduction steps:

• Open the Creative inventory, and navigate to the All tab to use the search function.
• Type some text in the search box, it can be anything really. The longer your query is the easier this is to reproduce.
• Go back towards the start of your search query and try to remove or add some characters. Note the delay.

I don't have video evidence, as my device doesn't handle nor support recording video well.
