[TECHNICAL SUPPORT] LPS-34764 Fixed _totalSize setting for large file sizes



Hi Sergío,

this modification is necessary to create a fix for the LPS for a previous version for the upload progress bar. However, the progress bar problem is not on master, this file size related problem can be a problem on master also. That is why we're sending this separately here.

I found the Document & Media Library component to be the closest one to this and I found you on that, this is why I'm sending this to you.

Regards
Zsigmond
