When trying to swap, portfolio page reloads causing the Swap button to change to Insufficient Funds momentarily but its quite prominent. We should make this more smooth so the button doesn't switch to Insufficient Funds

1. Select Swap of tokens
2. Click Swap to trigger panel to open
3. Briefly swap button changes to Insufficient Funds

Actual result:

Linux.mov

Expected result:

Better handling of UI

@srirambv Just tested this, seems like this is not occurring any more.
Might have been resolved by some other fix.
Are you able to confirm?

@Douglashdaniel yes the issue seems to be fixed now. I don't see the Insufficient funds message on the swap button when trying to swap. Closing as the issue is not reproducible anymore
