[UI]: 'back' return strategy don't work

[cybersanya]

Describe the bug

Default 'back' strategy doesn't redirect user back after connecting wallet or after transaction. Specifying returnStrategy with custom return url doesn't work either.

Expected behavior

After connecting wallet or approving/declining transactions users would be redirected back to my app

Current behavior

After connecting wallet or approving/declining transactions users stay in telegram app

2. Install and setup tonconnect/ui with zero config, only manifestUrl.
3. Open the app in any browser (or as telegram mini app)
4. Call tonConnectUI.openModal()
5. Select default wallet (Wallet on Telegram)
6. Confirm connection in telegram app
7. Redirect back doesn't happen
