Httpd jumps to 4GB in seconds - Memory leak when using backspace on the keyboard

Dear community,

Is this a Bug?

I have the following:

Within the table are around 100 name/results.

However, when I enter the Select box and use the BACKSPACE key to remove names (instead of clicking the (X) next to the name) I notice the httpd.exe process on my Apache shoot up from 100Mb normal operation to 4GB - that occurs within 60 seconds (closing the page does not release the memory) that is literally just from removing 30 names using the BACKSPACE key.

I have tried with the latest Select2 & CSS but to no avail.

Any ideas, it is definitely a problem with memory, but wonder if you guys see it?

Many thanks,
