Predictive text is erroneously inserted, when using backspace or typing "special" characters.

Behavior: When typing a word and then using the backspace key to delete it (partially or completely), the current prediction buffer (the word before cursor) is inserted, with the last character being stripped.
This also happens when appending interpunctuation (.;,), the space character and other "special characters" (e.g. ", ), (, ], [) directly to a word.
It does not happen when deleting a space character by using backspace or typing a "special" character after a space. It also does not occur when using an Android virtual keyboard (by the help of AlienDalvik Control) instead of the vKBD SailfishOS provides. And it never happens in native SailfishOS apps.
For example, if you type devices and hit backspace, it will become devicesdevice. Repeatingly tapping backspace will get you something like this: devicedevdevicede

Observed on SailfishOS 3.0.0, 2.2.x (and older versions) with some (but not all) Android apps, e.g. Firefox / Fennec and Here for Android on various devices (including Jolla 1, Xperia X).

P.S.: Now (right here, while typing this in Fennec) this issue occurs when hitting any key (even regular letters) on SailfishOS' vKBD after any character, except a space.

The similar problem is sometimes observed in whatsapp. Tapatalk works fine.

I cannot reproduce this issue in apps Whatsapp, Here WeGo and Aptoide. Does the issue keep occurring also after rebooting the device?

No, it doesn't.

I noticed, this issue appears randomly. The issue goes away itself after sending the message or restarting the keyboard (Settings -> Utilities -> Restart keyboard).

Also happens in Firefox and a couple of other Android apps.
Observed under SFOS 2.1.4 and 2.2.0, but apparently this bug exists since 2.1.0 and also in 2.2.1. Quite an annoying bug!
Note that one has to use the Backspace key on the vKbd to trigger this bug (as described in the original posting).

After updating to, I have been seeing this bug randomly a lot of times on android apps. Sometimes this bug persists even after multiple restarts making the android apps pretty much unusable.

Happens a lot in Firefox with many textareas. It's happening here, now. Jolla C. I've almost stopped posting on forums on this device.

I've updated the original description and changed the title of the question to reflect recent occurrence

Still present inin OS3 :(

Is it possible to disable predictive text? I'd do that if it would get rid of this bug?

@DaveRo: There's the App from the Jolla Store (simply search for predictive). Uninstall that and see if it helps. haven't tried it myself though.
The alternative Presage prediction engine from openrepos might provide an alternative. But i hasn't got as many languages as the Jolla one
