[Affected versions]:
- Firefox 59.0a1 (2018-01-09)
- Firefox 58.0b15
- Firefox 57.0.4

[Affected platforms]:
- Windows 10x64, macOS 10.12, Ubuntu 16.04x64

[Steps to reproduce]:
1. Launch Firefox.
2. Go to web.skype.com and login.
3. Click in the 'Type a message here' area and observe the pointer. 

[Expected result]:
- The pointer is correctly displayed. 

[Actual result]:
- The pointer has a missing pixel (see https://i.imgur.com/KhyupqD.png).

[Regression range]:
- It seems that is an old regression since the issue is also reproducible on Firefox 40.0a1 (2015-04-10). 
- I was not able to find the exact regression range since on older builds, web.skype.com does not work. 'Please update your browser to start using Skype.' message is displayed on older builds.

Could layout be a better module fit?

So, the missing pixel is from the placeholder "Type a message here", which turns white but still covers the cursor when the textarea is still empty.

I guess the fix is to paint placeholder under the cursor somehow.

Extremely old -- I can reproduce in a build from 2012-12-01 (Firefox 20.0a1), using the attached testcase.  And I can reproduce in builds a month or two older (at least) if I adjust the testcase to use single ":" instead of two, as the pre- bug 737786 placeholder selector.

I'll mark this as weakly depending on bug 737786 (related to that feature), and remove the regression flag, since this doesn't seem to be a regression -- just a bug.
