Thank you, Alice-san, the cell is ``` <div class="cell-input editable" tabindex="0" role="combobox" docs-unhandledkeys="ctrl+shift+z,ctrl+y,ctrl+z" id="waffle-rich-text-editor" style="background-color: rgb(255, 255, 255); font-size: 13px; color: rgb(0, 0, 0); font-weight: normal; font-family: "Arial"; font-style: normal; text-decoration-skip-ink: none;" dir="ltr" g_editable="true" aria-autocomplete="list" aria-label="C6" contenteditable="true" >a<br><span style="font-size:13px;color:#000000; font-weight:normal; text-decoration:none; font-family:'Arial'; font-style:normal;text-decoration-skip-ink:none;"></span></div> ``` And we had not supported `white-space:pre-wrap` in editor since bug 1724650. So that I guess that they use a specific path for Gecko and that depends on some bugs of Gecko (our editor does not refer CSS in most cases, that makes web developers confused like checking the `<br>` element is visible or not).
