Search Images inside old Media Library with alt text not working correctly

When i'm trying to search image througth Media Library using alternative text. It looks like only the first word is considered for my search.
My projet is running on old Page Builder and old Media Library. Everything is working fine on another projet i have on the new Page Builder.
Thx for your feedback

Hi Simon,

We have just launched the improved search for the new builder and we'll be happy to enable it on your repo here:

The old editor and old media library are now deprecated and will receive no further updates.
