Our CSS currently contains this large block, probably copy-pasted from multiple web resources:
overflow-wrap: break-word; -moz-appearance: textfield-multiline; -webkit-user-select: text; /* stylelint-disable-next-line font-family-no-missing-generic-family-keyword */ font: medium '-moz-fixed'; /* stylelint-disable-next-line font-family-no-missing-generic-family-keyword */ font: '-webkit-small-control'; font-size: medium; line-height: normal; color: initial;
The intended effect of this code is to make a <div> appear like a <textarea>, but without the border.
Following the same arguments @Volker_E gave in https://gerrit.wikimedia.org/r/433150 we find it critical to reduce this code to the smallest subset actually needed by our supported browsers. Code comments should explain which subset is required for which browser.
This came up (again) while working on T205431.
