Side-Nav-Inner-Toolbar Doesnt Expand on Initial Load (Mobile Portrait View)

[ming-s]

Hello,

It looks like Devextreme-cli react template inner-toolbar doesnt expand during initial load (in Mobile Portrait View). See attached video capture. We are able to reproduce this issue on newly created template "npx devextreme-cli new react-app app-name". The issue appears on side-nav-inner-toolbar template in mobile-view (Portrait mode). The problem doesnt appear in Landscape mode though. Actually, after Landscape mode, the sidebar works in Portrait mode. Clearing the cache will initiate the issue again in Portrait mode.
