Hi.
This issue seems to occur again in the latest version.
It has been fixed in version 2.5.2, but it seems to have a problem again in the latest version.

[wacky6]

This is strange, el-input receives no change after 2.5.0 release.

@wacky6
Version 2.5.4, not only <el-input> has IE Korean entry bug, The <el-transfer>, <el-select>, if there is a _filterable_ attribute, this bug will also occur, but <el-select> if When there are _filterable_ and _remote_ attributes, will no problem. hope to reopen this issue

[wacky6]

Then please provide your OS, browser, Korean IME name and version. And the step to reproduce.

We will reopen this if it is common. If only one IME is buggy, we won’t fix it.
