@paul-griffith

I have the following error in browser dev console an some of my icon library are not rendered in the perspective page.

**QuotaExceededError: Failed to execute 'setItem' on 'Storage': Setting the value of 'bootstrap|1-square' exceeded the quota**

**bootstrap|1-square** was well rendered

I use lots of icon library quite large.  
I don't have any issue in the designer.

Is there a setting to increase this limit ?

Full error log:

oops seems to be a browser limitation, around 5Mo if it use a sessionStorage ?

Not my area of expertise - can you make a support ticket so the right folks can evaluate if this is a bug or just a potential optimization?
