--- Comment #1 from Carlos Garcia Campos <cgarcia at igalia.com> ---
This is not GTK specific, but it's more noticeable because we use white color for the selection text foreground. This regressed in r286955, because in case of text with decorations, the foreground text is rendered in the same coalesced marked text loop than the decorations and StyledMarkedText::coalesceAdjacentWithEqualDecorations() doesn't take into account the text styles. So, when we start rendering from the beginning of the line, only one style marked text is generated and the whole line is painted with the selection style (white foreground), on white background it looks like the non selected text disappears. When we start selecting from the end of the line, a single styled marked text is generated, but the selected text is painted with the non-selected style, and it becomes white once we complete the line selection.
