Current Behavior

When the keyboard is dismissed by tapping the background (input blur) and the same (or another) input is re-focused quickly (within ~1 second), the keyboard initially reserves more vertical space than it actually needs. A few milliseconds later the reserved space corrects itself to the true keyboard height, producing a visible double jump of the webview/layout.

The issue is timing-dependent and only reproducible with a specific dismiss method:

✅ Happens: dismiss via background tap (input blur) → quickly re-focus input ❌ Never happens: dismiss via native back button → re-focus input (any speed) ❌ Never happens: background tap dismiss → wait 1–2 seconds → re-focus input

The issue also appears to depend on the keyboard app — specifically on whether it renders a suggestion strip above the keys:

✅ Reproducible on Gboard (has suggestion strip) ✅ Reproducible on SwiftKey (has suggestion strip) ❌ Not reproducible on a keyboard without a suggestion strip — rapid re-focus resizes correctly out of the box

Expected Behavior

Re-focusing an input immediately after a blur-based dismiss should resize the layout once, to the correct keyboard height — identical to the behavior after a native-back dismiss or after waiting between taps.

Additional Information

Steps to Reproduce:

• Create a page with a text input and enough empty background area to tap.
• Tap the input → keyboard (e.g. Gboard or SwiftKey) opens normally.
• Tap the background to blur the input → keyboard closes normally. ✅
• Immediately (within ~1s) tap the input again.

Observe: the layout jumps up more than needed, then a few milliseconds later snaps back down to the correct keyboard height → visible double jump.

To confirm the timing dependency, repeat steps 3–4 but wait 1–2 seconds before re-focusing: the keyboard opens with a single, correct resize every time.

To confirm the dismiss-method dependency, dismiss with the native back button instead of a background tap: rapid re-focus works correctly every time.

To confirm the keyboard dependency, switch to a keyboard app without a suggestion strip and repeat the rapid re-focus sequence: the layout resizes correctly in a single step every time.
