Timeout warning Classic Vs Fluid HCM 9.2 Image 48 and Tools 8.60.15

We just went live with HCM 9.2 Image 48 and Tools 8.60.15.

it was fluid implementation for ESS and MSS and certain custom admin components in Fluid.

Problem: When administrative user logs in and opens multiple tabs, (mix of classic and fluid pages), for example they open first 2 tabs with fluid pages, and next 8 tabs with classic pages, now they are active on 10th classic page tab, they are entering data on the this page. meanwhile first fluid tab has timeout warning, which they can't see upfront, because this warning pop-up is on the page. Unaware of this warning, user is still active on the 10th tab, and suddenly it kicks them out of the session, loosing their unsaved transaction data.
