When Spam Scores enabled unable to scroll Junk folder when message is selected

[drwonky]

Describe the bug
If you select a message in the message list in the Junk folder, you cannot scroll the list whereby the selected message is outside of the viewport.

Reproduction steps

• Enable spam scores extension
• Go to the Junk folder
• Click on a message
• Try to use the scroll bar or mouse wheel
• You cannot scroll, the viewport "rubberbands" back to having the selected message shown

Expected behavior
Normal behavior is that selected message scrolls outside of the viewport and a "shadow" cursor follows the mouse. This is what happens when the plugin is disabled.

Screenshots
A screenshot wouldn't be helpful, the problem is only demonstrable interactively.

Thunderbird (please complete the following information):

• OS: Fedora 34
• Version: 102.1.2 (64-bit)
• Package directly downloaded from Mozilla

Spam Score add-on (please complete the following information):

• Version: 1.4.1

Additional context
Plugin works fine otherwise, the only issue I notice is the scrolling issue. Problem abates when disabling the plugin.

Same here. Also CPU spikes to constant 100% while rubberbanding.

On TB 91.x downgrade to v1.4.0 solves the issue for the moment. Removing the bugfix from 1.4.1 in a custom XPI for 102.x also works.

Removing the bugfix from 1.4.1 in a custom XPI for 102.x also works.

Hello @de-es - can you possibly send me (somehow?) this custom XPI so I can run tests on Thunderbird v102.x?

I'm experiencing similar (maybe?) symptoms described in this issue, but in a (somewhat?) different usage scenario/context. Specifically: when I sort on the Spam Score column in any folder, things get wonky (and I'm unable to scroll the msg-list window in the folder well, etc).

[de-es]

Sure. Just rename the file extension from .zip to .xpi and you should be able to install it.
spamscores-czaenker.zip

Thank you @de-es -- the install of the above file worked. Initial testing shows no problematic syptoms (that I reported earlier) while running Thunderbird v102.5.0 (on macOS v12.6.1 build 21G217).

Thanks again!

@friedPotat0 -

It seems clear that Spam-Scores v1.4.1 may have introduced a problem (even though it may have fixed another problem(s)). Could you possibly mark this as an opportunity for a future fix?

In any case, if you need more info to help solve/fix/process, pls let me know and I can work to provide more context.

Thanks for making such a great Thunderbird Add-On/Extension!
