Linetype shader intentionally switches behavior with zoom

FFZA10JGSJ1-60-12TC板图.zip放大缩小的时候线段会消失，且放大缩小应该是在鼠标点进行放大缩小比较好

@yanzexuan1 It looks like At AcTrLinePatternShaders.ts (line 91), zoom controls whether patterned lines are drawn as solid vs dashed. When crossing that threshold, short segments can appear to “disappear” (they land in gap phases and get discarded at AcTrLinePatternShaders.ts (line 106). If I force using LineBasicMaterial, then the issue disappears.
