Hi @CKoerner_WMF ,
looking at this but cannot reproduce it. Can you still reproduce it on your side? Which version of chrome do you use?
Thanks

Because https://en.wikipedia.org/wiki/User:Adithyak1997/common.js and lots of other stuff.

@Aklapper, so you mean I need to clear those files and check it?

You don't have to clear common.js if you follow https://www.mediawiki.org/wiki/Help:Locating_broken_scripts . Not sure if that also covers common.css so you may want to clear that.

In any case we need steps that allow reproducing that lots of text is small and lots of text is large. Because I cannot reproduce...

Actually, I have followed the instructions provided in the link https://www.mediawiki.org/wiki/Help:Locating_broken_scripts. The result was same as

The problem in that screenshot above is not only small Thank confirmation text but also small radio buttons between "(cur | prev)" and the date, and small stuff in the box at the top, and the top bar, and small stuff in the side bar.

When checked at the time of posting this task, it was only the Thank and Cancel buttons that appears to be too tiny. Now, it's including current and previous also. I think the texts current, previous as well as the thank and cancel buttons (these two appear when I press the Thank button) needs to be made of the same size as that of other texts.

Ah! I could finally reproduce this in Chromium 73 only when using the device toolbar to change its width. Confusing that it didn't work when just reducing the browser window size width. Sorry that I didn't try that earlier (Firefox does not behave like that)!

Not sure why this was proxied to Phabricator. :)

I'm confused by this. Should I have done something differently? Was my description not well understood? I want to improve my bug reporting skills. :)

(@CKoerner_WMF: I wrote that as the reporter has a Phab account I guess)

I don't think this is only effecting Chrome (Blink) users. I'm able to reproduce on iOS using Safari (Webkit). I see this behavior when both logged out and logged in. As you can see it's also effecting other links such as "Cur, Prev, and Undo" as Andre pointed out. So not Thanks-specific and not Chrome specific. :/

I can not reproduce it on the desktop version of Safari using the developer "Responsive Design Mode" which emulates a mobile device.

Change #1343224 had a related patch set uploaded (by Sanskardubey; author: Sanskardubey):

[mediawiki/extensions/Thanks@master] Thanks: keep Thank link size consistent on narrow WebKit
