On my Xperia 10 with Sailfish X, Android webview seems not working properly, is there any way to fix this?

Device: Xperia 10 Dual SIM (I4113)
SFOS version: 3.3.0.16

Hi

I recently changed my Xperia X to Xperia 10. Most functions go well but Android apps using Webview always newly open external browser even when app setting is to open inside app.
For example, tapping Feedly’s “VISIT WEBSITE” button on Xperia X goes to the site inside the app but on Xperia 10 external browser opens if Android browser app installed. Also if there’s no Android browser installed, Feedly goes to background but nothing happens on Xperia 10.
I feel it strange behavior and want to know if there’s any way to fix this to behave like that on Xperia X. (Hopefully without re-flashing, but it’s ok if it is the only thing I can do.)
Already tried uninstall & re-install of Android App Support / Aliendalvik Control.

Thank you.
